S&S 89″ EVO Stroker Build Part One

S&S 89" EVO Stroker Build

(Step 1) Here’s the right half of our 1998 EVO-powered Road King’s crankcases. Note the area that the crew at S&S machined out of the inner face of the crankcase. This was done so the new stroker flywheel assembly has the room it needs.

Though it doesn’t say so in the headline, this two-issue engine build is part of our ongoing series on rebuilding a 1998 Road King from front to back. The reason for this series is simple: some of our readers prefer a motorcycle without all the electronics of a modern bike, which means they’re looking to buy and rebuild one of the Evo-powered Harleys of the late 1990s. To that end, we’ve been slowly rebuilding and upgrading a 1998 Road King over the last several months. In this two-part series, we’re going to rework the bike’s engine.

Though a stock or worked 80″ Evolution is a good engine, we wanted to kick it up a few notches while still keeping the engine dependable. In fact, this engine was just that: a worked but tired 80″ with a hot cam, SE heads, and a S&S billet oil pump. The bike’s owner requested more cubic inches so he would have no problem keeping up with his Twin Cam-powered buddies. Having used S&S Cycle parts in my high-performance bikes for over 40 years, S&S was my go-to company for an 89″ stroker kit with a matched set of supporting performance components. When making a major modification like a stroker kit, the engine’s other performance components need to complement the upgrade, so that you end up with a strong running and trouble-free engine. Let’s talk about those flywheels first.

S&S 89" EVO Stroker Build

(Step 5) Once the new connecting rod bearings have been fitted to the new S&S crankpin, the flywheels, connecting rods, crankpin and all the bearings and their cages are assembled.

The flywheel kit we stuffed into our stock H-D crankcases is one of S&S’s 89″ Stock Bore Stroker Kits for 1984-99 Carbureted Big Twins (#32-2230/$1,134.95). What all that means is we reused the stock H-D cylinders, but we swapped out the stock 4-1/4″ stroke flywheels for a set of S&S 4-5/8″ stroker flywheels. Increasing the engine’s stroke, which is how far the pistons move up and down in the cylinders, increases the engine’s displacement. With these 4-5/8″ stroke flywheels, the pistons move 3/16″ farther up and 3/16″ farther down the cylinder’s bore, which increases the engine’s total size by about 9 cubic inches! In any engine that will result in a nice power boost! And though this setup requires some minor crankcase and cylinder modifications (mods that can easily be done with hand tools), just swapping out the flywheels for longer stroke versions is an economical way to increase the displacement of your engine. This flywheel kit also comes with a set of S&S heavy duty connecting rods, as well as S&S sprocket and pinion shafts, all assembled, balanced, trued, and ready to be installed into a set of cases. Since the pistons will be moving deeper and higher in the cylinders, special pistons, which must be ordered separately, are required but we’ll talk about those in the next issue.

As for the cam we decided to roll with, an S&S 561 (#33-5076/$189.95) was a perfect match for what the owner wanted from his new motor. This cam fits 1984-99 Big Twins and is designed for 88″-96″ engines with a 9.5:1-10.5:1 compression ratio. We wanted the 561 because it produces strong power right in the 3000-5500 rpm range. This is a Road King, not a racing bike. With the cam kicking in at 3000 rpm, the owner can cruise all day long below 3000, which is where cruising is done, without gobbling fuel. But when he wants to pass a truck, get on a highway, etc., a simple twist of the wrist brings the cam in with the resulting boost in power. The 561 requires hydraulic tappets and valve spring spacing, which we’ll also cover in the next issue when we install them.

S&S 89" EVO Stroker Build

(Step 10) The stock left case is then positioned onto the flywheel assembly, so the outer Timken bearing can be pressed onto the shaft. The bearing endplay is then checked using a special fixture and a new shaft seal installed.

As for who would build our engine, we went right to the source: S&S Cycle! The S&S Service & Speed Center will install any product S&S sells onto your engine, as well as rebuild all S&S engines and other products (carbs, etc.). However, they’ll also rebuild 1966 and later Harley Big Twin engines, and 1948-99 H-D Big Twin and 1957-85 Sportster flywheel assemblies, and a whole lot more. We shipped the S&S Service & Speed Center the engine components they requested and what we got back was an engine ready to be bolted into the frame. The accompanying photos and captions show many of the steps S&S takes to install one of its stroker kits into a set of stock Harley-Davidson crankcases. In the next issue, we’ll show you how the top end was overhauled and assembled. – AIM

Spring Prep: Top 10 Checks to Get Your Bike Ready to Ride

American Iron Garage

At this point in our riding careers, we have a pretty good handle on the necessary precautions and checks and yet, every so often we’ll have one of those infamous “oh $#!#” moments. Sometimes it can happen in the garage or driveway, other times it can happen out on the road. Those moments suck, so we’ve compiled a list of ten basic, and some unusual, points to check before heading out for that very first ride of the season, or any ride for that matter.

Going to Daytona Bike Week – Motorcycle Packing Tips

If you are packing up your motorcycle to head down to Daytona Bike Week this week, here is a great list of suggestions and ideas on how and what to pack.

Tips to pack for a motorcycle tour


  • Lightweight synthetic clothing – such as T-shirts and underwear – can be washed in a hotel sink and dried overnight (cotton fabrics take too long to dry in this manner).
  • Zipper-lock plastic bags of various sizes can be used for organizing items in saddlebags and duffle bags. They can make it easier to find and retrieve particular items without unpacking your entire motorcycle. Use the one-gallon size to pack one day’s worth of clothes – jeans, undergarments, and shirt. This makes it easier to unpack just what you need.
  • Don’t fold your clothes – roll them. They take up less space that way.
  • Pack items that have more than one use. A multi-tool is handier than a basic pocket knife.
  • When traveling with other riders, conserve space by comparing packing lists and eliminating duplicate items.
  • When traveling (two-up) with a spouse or “significant other”, can you share a tube of toothpaste and shampoo for a week.
  • On long trips, consider bringing your rattiest underwear (or other clothing), then just throw it away when you’re done with it!
  • Don’t forget power cords and chargers for your cell phone and other electronic devices.
  • Check the cargo weight limits of your bike – as wells as the bags and racks – and adjust tire pressure and suspension accordingly.
  • Few things are as easy to pack as money or credit cards. If you’re struggling with whether or not to bring a particular item, consider simply buying it on the road if you need it.
  • If you watch the ounces, the pounds will take care of themselves. When possible, lighter is better.
  • When loading your bike, keep as much weight as possible close to the bike’s center of gravity. That means low and toward the tank, distributed evenly from side to side.
  • A day or two before you leave, do a dry run. Pack the bike and go for a short ride, then adjust the load as needed.
  • If you’re camping, set up your tent once or twice before you leave (and don’t forget to waterproof it). Practice setting it up in the dark.
  • With your bike fully loaded, check your headlamp to make sure it’s properly aimed.
  • Pack all your cold weather and raingear (raingear on top) no matter what time of year it is.
  • Plastic bags make great boot liners if you forgot your gaiters. If you forgot your rain gloves, rubber dishwashing gloves are cheap and easy to buy.
  • A small towel can be wrapped around your neck during a rainstorm to keep water from running down your back – and doubles as a shop rag.

Official 2017 Bike Week Build: Badazz Powdercoating, House of Kolor, Prokop Signs

Believe it or not, Bike Week 2017 is almost upon us. We can’t wait, not only because we’re ready to ride again, but because we’re eager to find out who’s going to win the Official Motorcycle of Bike Week 2017.

We can’t say enough for the team at Street Stuff Cycles. Talk about coming through big time! Not only did they put the pieces of the puzzle together, they even painted the bike in-house! Now that’s skills!

Striping up the 2017 Official Motorcycle of Daytona Bike Week

The finished project came out looking so good it’s featured on the cover of American Iron Magazine Issue #347 on newsstands now, so be sure to grab a copy and check it out. A trio of companies contributed to its curb appeal, House of Kolor, Badazz Creative Coatings, and Prokop Signs. Here’s what American Iron’s Assistant Editor Stephen Long had to say about the collaboration in his magazine write-up.

Ah….the paint. Rich lays down the skins in a room we hear is more akin to a Cold War-era bunker, though maybe a little more colorful.

Many a late night was spent in the shop, and none seemed quite as pressing as Rich and his work with the paint. Turning to House of Kolor, same as the ’06 Bike Week build, he mixed and mixed and mixed, hoping to find the right color combination.

“I worked with a technician at House of Kolor, trying to figure out a mix of the candies and the flake,” said Rich. “You know, it’s not just one color out of a can. It’s nine different colors that we used to come up with that shade.”

Eric Crayson tightens down the tank with its new House of Kolor paint and Prokop Signs graphics.

Badazz Creative Coatings played a major role in its transformation, too. The list of parts Badazz powdercoated in shimmering “Black Ink” is long, from the Lindy Bar protecting the engine to the mount for the top case to assorted levers, covers, and brackets. In the end, the only shiny parts on the bike are primarily machined edges or contrast cut covers.

Badazz Creative Coatings 2017 Official Daytona Bike Week Motorcycle

From fender supports to levers to highway bars, Badazz Creative Coatings had plenty to powdercoat on the 2017 Official Daytona Bike Week Motorcycle.

The final pieces of the design puzzle came from Prokop Signs out of Norwich, CT, including the 76th anniversary Daytona Beach Bike Week logo on the tank. There’s also plenty of succinct striping separating the primary colors. And those colors. You really need to see this thing in the sunshine to admire how the flake pops!

Prokop Signs Official 2017 Bike Week Motorcycle

Prokop Signs provided the graphics on the Official 2017 Bike Week Motorcycle.

There’s still time to get in on the drawing for this motorcycle because tickets are on sale until Friday, March 17 at 4 p.m. (EST) at OfficialBikeWeek.com They’re $50 each, or three for $100. Come Saturday, March 18, one lucky person will be the proud new owner of this sweet, one-off custom 2010 Harley Ultra Classic Electra Glide. We hope it’s you!





Official 2017 Bike Week Motorcycle: Coastal Moto Largo 3D Wheel & Metzeler ME888s

The clock is ticking. Chances to win the Official Motorcycle of Daytona Beach Bike Week 2017 are dwindling down. The winning ticket is going to be drawn March 18 and somebody is going to be riding away with one sweet customized, collectible 2010 Harley Ultra. Only 1708 tickets have been sold as of two days ago, so you do the odds. Tickets are $50, but if you buy two you get an additional entry into the drawing. This thing is a real runner, with parts from Bagger Nation, Arlen Ness, Klock Werks, Cobra USA, Harley-Davidson, ASA Electronics, Hogtunes, Kuryakyn and others.

Amongst those others is Coastal Moto who provided a fantastic looking 21” Largo 3D front wheel for the project. Coastal Moto touts the Largo wheels as having “full 3-dimensional design elements that continue all the way out to the edges of the rim. These 3D elements have never been possible to achieve in the industry standard CNC machined forgings. These wheels also accept 2014-Up style OEM brake rotors, so you can use your stock rotors and save huge bucks there as well, plus ABS wheels ship with Intelligent ABS pre-installed so there is no need to recalibrate your ABS system on linked brake models. These babies arrive totally pre-assembled with bearings and valve stems, and are ready to roll.”

The new 2017 Official Daytona Bike Week Motorcycle is rolling large up front thanks to the new Coastal Moto 21″ Largo 3D Wheel and Metzeler ME888 tire.

A new wheel deserves new rubber so the team at Street Stuff Cycle slapped on a new Metzeler ME888 Ultra Marathon on the Largo 3D front wheel. Metzeler’s ME888’s are ultra high mileage tires, the 888’s sporting a new wider and shorter footprint area, X-Ply carcass profile and geometry, and a fresh tread design aimed at improving wear. The rear received a new Metzeler ME888, too.

The 2017 Official Bike Week Motorcycle is featured on the cover of American Iron Magazine Issue #347 on newsstands now. Be sure to grab you a copy to see it in its fine final form with its sharp House of Kolor paint artistically applied by Street Stuff.

Official 2017 Bike Week Build: Arlen Ness Bagger Apes, Hill Country Custom Cycles Wires

Arlen Ness Modular 13" Bagger Apes and 10-Gauge Billet Grips

A set of Arlen Ness Modular 13″ Bagger Apes and 10-Gauge Billet Grips complement the cleaner, more modern look of the 2017 Official Daytona Bike Week Motorcycle.

Come March 18, somebody is going to be shouting from the rooftops! Why’s that, you say? Because that’s the day someone will have won the keys to the 2017 Official Daytona Bike Week Motorcycle, that’s why. March 18 is the day when the winning name will be drawn at Riverfront Park in Daytona Beach for the customized 2010 Harley Ultra that’s undergone a transformation from a stock bike to a one-off collectible custom.

The build wouldn’t be possible without the talented team from Street Stuff Cycle out of Norwich, CT. The Crayson family has stepped up huge in putting this bike together and American Iron is proud to have partnered with them. They’ve impressed us with their skills while giving this bike a complete overhaul, from wiring to bodywork to paint.

And when we say this thing’s been given the complete overhaul, we mean it. This includes doing away with the stock bars for a set of Arlen Ness Modular 13” Bagger Apes. Not only do the Ness bars give the bike an edgier, more aggressive look, but they can easily be tailored to a rider’s preference thanks to billet aluminum junction clamps. This allows riders to adjust the angle of the controls to the most comfortable position in addition to the entire handlebars capacity to be moved forward or back. The Ness bars are drilled and slotted so you can run wiring internally, keeping everything clean and tidy. And what better to pair the Modular 13” Bagger Apes with than a set of Arlen Ness 10-Gauge Billet Grips?

Hill Country Custom Cycles brake hoses

The 2017 Official Daytona Bike Week Motorcycle receives new brake hoses and wires courtesy of Hill Country Custom Cycles.

Since the bars were already set up to run all the wiring internally, that’s exactly what Street Stuff did. Instead of reusing the old wires though the 2010 Harley Ultra got a fresh set from Hill Country Custom Cycles. Hill Country has some great complete ape hanger kits, but since we already had some Ness Bagger Apes we opted for a fresh set of wires and brake hoses. We weren’t kidding when we said this bike’s been gone over with a fine tooth comb!

So how do you go about winning this bike? Go to OfficialBikeWeek.com and buy your ticket! Tickets are $50 each, but if you buy two, you get an extra entry into the drawing. You don’t have to be present to win and only 4500 tickets will be sold. Thing is, this drawing is going to be held whether all the tickets sell or not, and the odds right now are pretty darn good! Time’s a tickin’ so get you ticket today.

Looks like fun, doesn’t it? Luckily Eric Crayson of Street Stuff Cycles was on top of things while rewiring the 2010 Harley Ultra with a fresh set from Hill Country Custom Cycles.

Official 2017 Daytona Bike Week Build Audio: ASA Electronics, Hogtunes, Kuryakyn

Arlen Ness. Paul Yaffe’s Biker Nation. KlockWerks. Cobra. Harley-Davidson. If this isn’t an impressive list of contributors for the 2017 Official Bike Week Motorcycle, we don’t know what is. This is evolving into no ordinary 2010 Harley-Davidson Ultra. The team at Street Stuff Cycle in Norwich, CT, have been doing an incredible job of turning this tourer into a real runner, high in style and performance.

Keeping up with current trends, the 2017 Official Bike Week Motorcycle has been outfitted with a boomin’ audio system. This bike is built for the long haul, and jamming out to your favorite tunes is a great way to melt the miles away.

Jensen HD1BT Stereo for 2017 Official Bike Week Motorcycle

Thanks ASA Electronics for sending over a new Jensen HD1BT stereo for the 2017 Official Bike Week Motorcycle.

For starters, the good people over at ASA Electronics sent us over a new Jensen HD1BT stereo. One of the best things about the HD1BT is it’s the “first true replacement radio made to fit into a Harley-Davidson factory opening without requiring any special mounting kit or brackets.” Like the factory stereo, it can operated through the handlebar controls. In addition to its standard AM/FM tuner, riders can stream audio through Bluetooth or plug in their iPhone or iPod directly. It’s Sirius XM-ready and has weather band with S.A.M.E. weather alert, a particularly handy feature for bikers.

Hogtunes 200-watt amplifier on 2017 Official Daytona Bike Week Motorcycle

A 200-watt Hogtunes amplifier is going to make the 2017 Official Daytona Bike Week Motorcycle go Boom! 

The new Jensen stereo is going to sound great pumping out of new speakers from Hogtunes. Inside the fairing sit two 5 ¼” speakers, the Hogtunes Front Speaker Kit coming with a 200-watt, 2-channel amplifier. If that wasn’t enough, the custom Ultra has been outfitted with a set of Hogtunes 200-watt 6×9 Saddlebag Speaker Lids. The saddlebag speakers are divided into 1.25” tweeters and a 6×9 woofers. The speakers are weather resistant and the lids seal up tight so no water gets into the saddlebags. Rounding out the new audio package is a Kuryakyn Dual Function Flexible Antenna. At 17” tall, the Kuryakyn antenna is clean and compact. Needless to say, with this sound system, the 2017 Official Bike Week Motorcycle is going to thump!

Hogtunes Speaker Lid install

The Hogtunes Speaker Lids feature a 1.25″ tweeter bridge and a 6×9 woofer.

So how do you get in on this action? Simply go the OfficialBikeWeek.com website and click Enter to Win a Cycle. You can’t miss it. Tickets are $50 each, but we’ll let you in on a little known secret. For every two tickets purchased, you get an additional entry. The winner will be drawn Saturday, March 18, 2017, at Riverfront Park on Beach Street in Daytona Beach.

Official 2017 Daytona Bike Week Build: Klock Werks Flare Windshield

The 2017 Official Daytona Bike Week Motorcycle is accumulating quite the pedigree of parts. The tried-and-true stock Harley Ultra formula looks much sportier thanks to the Paul Yaffe Bagger Nation touch, including a Chupa Rear Fender, Super Stretch Saddlebags, and Razorback Gas Tank. If getting upgrades from one custom bike building legend wasn’t enough, it’s also got traces of the incomparable Arlen Ness in its design straight from Arlen Ness Enterprises red hot 10-Gauge line of parts, the front seeing the addition of 10-Gauge Hot Legs and Fork Boots while the engine, tranny pack, and primary all don 10-Gauge covers. The 2017 Official Daytona Bike Week build is now not only starting to look the part, it’s running like a top thanks to an RPT Air Intake, Power Port Dual Headpipes, and Race-Pro 4” Slip-Ons from Cobra USA.

With the likes of Yaffe and Ness already associated with the bike, it’s only fitting to add the name of another custom building heavyweight to the mix – Klock Werks. The company’s Flare Windshield is one of the best on the market, with an aerodynamic design that’s been tested in wind tunnels. It’s got the “Flip” at the top that reduces turbulence on riders and “Hips” on the sides that routes wind away while adding downforce to the front end. In our opinion, it looks pretty darn sharp, too. Klock Werks is celebrating its 20th anniversary in 2017, and you don’t enjoy that type of longevity in this industry without manufacturing quality products.

Klock Werks Flare Windshield Install 2017 Official Daytona Bike Week Motorcycle

Eric Crayson of Street Stuff Cycle tightens the screws of the Klock Werks 3.5″ Dark Smoke Flare Windshield onto the 2017 Official Daytona Bike Week Motorcycle.

Street Stuff Cycle’s Eric Crayson slapped it onto the stock Batwing fairing in a jiffy and added some Klock Werks Contrast Cut Trim for good measure. We can’t wait to see the look on the face of the person who wins this bike! As of 12/28/2016, only 563 out of 4500 tickets had been sold, and this bike is going to be raffled off whether it reaches the maximum or not, so chances of winning could be even better.

If you’d like to get in on the 23rd annual drawing, head over to OfficialBikeWeek.com to buy your tickets. You don’t have to be present to win, so even if you can’t make it to Daytona Beach Bike Week this year, you can still ride away a winner.

Official 2017 Daytona Bike Week Build: Harley-Davidson Genuine Accessories

Harley Slotted Black Anodized Shift Linkage

A Slotted Black Anodized Shift Linkage from Harley-Davidson is installed on the 2017 Official Daytona Bike Week Motorcycle.

While Christmas may be over, it’s going to feel a lot like Christmas come March for whoever wins the 2017 Official Daytona Bike Week Motorcycle. American Iron has been overseeing the project as the team at Street Stuff Cycle has been busy transforming a stock 2010 Harley Ultra into a sweet one-off, top-shelf tourer. The raffle is limited to 4500 tickets with the winner slated to be drawn March 18, 2017, at Riverfront Park on Beach Street in Daytona Beach.

The project is coming together nicely thanks to a slew of new parts from Arlen Ness Enterprises, Paul Yaffe’s Bagger Nation, and Cobra USA. Seeing how the base model is a 2010 Ultra, not having some pieces out of the monstrous Harley-Davidson Genuine Motor Parts + Accessories catalog would be sacrilegious. The Motor Company was more than happy to step up and support the project, and sent over a pair of Burst Shifter Pegs and a Burst Brake Pedal Pad for starters. The new Harley Slotted Black Anodized Shift Linkage looks sharp, and we “can see clearly now” thanks to a set of Fairing Mount Mirrors that slipped right in to the Ultra’s Batwing fairing. Harley-Davidson also sent over a host of replacement gaskets, including the primary cover, rocker cover, head to rocker base gaskets, and ones for the head exhaust port.

H-D Oil Temp Gauge Install (Intro)

2005 Electra Glide Harley Oil Temp Gauge Install

Our 2005 Electra Glide is up on our mechanic Chris’ lift with a drain pan under the tranny and the seat removed. The battery ground cable has also been disconnected.

By Chris Maida

Swap out that air temperature gauge for a much more useful oil temperature gauge!

H-D Oil Temp Gauge Install preview

Using a 5/8” socket and 5/16 Allen, Chris removes the engine oil drain plug (right hole) and oil pan plug (left hole) from the engine oil pan under the tranny.

If you own a twin cam touring model with a fairing, you have the not-so-useful air temperature gauge that comes standard with the gauge package. But do you really need a gauge to tell you it’s 100 freakin’ degrees out? A much better use of that gauge spot is an oil temperature gauge. This setup gives you valuable info during your ride on how your engine is operating, especially on very hot days. This upgrade is not hard to install and can be easily done right in your own garage, not taking more than half a Saturday to complete. In fact, you should do it at the same time you’re changing the engine oil and filter, since you’ll be draining the oil anyway to install the kit’s temperature probe.

Electra Glide engine oil drain plug Harley Oil Temp Gauge Install

Here is the engine oil drain plug (bottom) with its magnetic tip to catch any ferrous metal slivers from the oil. The top must be removed to install the oil gauge sensor.

Since we’re going to install our kit onto a 2005 Electra Glide, we went with a black-face 2″ diameter oil temperature gauge (#70900283/$149.95), which is styled to match the original equipment gauges on our Electra Glide. This gauge kit, which is also available with a silver or titanium face gauge to match other models, fits 1999-2013 FLHT, FLHTC, FLHTCU, FLHX, FLTR, and Trike models. However, it doesn’t fit 2009 and later CVO models. The kit includes the gauge, wiring harness, and all needed hardware. Check out the accompanying photos and captions to see just what it takes to install this very useful gauge. AIM

Harley Oil Temp Gauge swap out for air temperature gauge

Chris uses an 11/16” wrench to install the supplied oil gauge sensor/brass bushing into the oil pan. Tighten the bushing, not the sensor, until it’s snug in the pan. This as a tapered busing, so don’t kill it!

The new gauge goes into the inner fairing and into the gauge bracket just like the stock unit. Chris aligns the tab on the gauge with the notch in the fairing to properly position the gauge in the inner fairing.
