Smile Advice on the SE Heavy Breather

Thanks Senior Frisco, for the review and things to look out for, I appreciate the responce. What is the high speed plug check? Like I said I will get back too everyone on my SE HB application, to let everybody know if I had to go the EFI Tuner way or not. Check out my ride, I posted it on my profile.

Hey Super

I got your visitor message and sent you an e mail explaining the check,, I didn't see your last post here yet, heck,,,,, I'll just post it here too..

The test is done this way..
Get out on the highway and do about 80+ for about 15 miles.. Do Not fluctuate RPM's,, try to find a road and time of day to do this without getting a ticket..

Look ahead for a spot/exit etc. to pull over safely then pull in clutch (dis-engage) and Switch Off ignition at the SAME time.. DO Not shift gears or ANYTHING.. Just simply coast and pull over to park..
Get out your gloves and a wrench to pull your plugs..
What you will see is a Snapshot of your A/F mixture at the steady RPM that you were going..
If the porcelain is snow white (what the EPA wants) your A/F is very lean.. Even though the newer sickles like yours are said to be correct at what is called a "lean burn" A/F mixture, I and many others dis-agree.. If it is sooo good then why are soo many guys finding ways to re-adjust it..?!
A lean Mix is a lean Mix and that can cause damage and loss of performance..
A good color is gray to light brown..
There are other things to look for and ways to interpret the plug colors but this will get you a ball-park idea how your A/F mix is..
Then if you choose you can ride home at a lower RPM (steady if you can) to get an idea what your lower RPM mixture is like..
This works on all carbs and EFI, doesn't matter,, Mixture is mixture..
Then it'll be up to you to do something about it if you so choose..

Have a ball

Hay Frisco,

My grandpa was a mechanic and taught me a few things; one of which was that a high speed test on the engine can also be performed at a lower speed by staying in a lower gear and run the rpm's up to where they would be at the higher speed. the only real difference there would be that the wind resistance and pull on the motor from the tranny would not be exactly the same. He did this because all he had was narrow back roads to drive on, (and probably to keep from getting tickets too).
first ya gotta know what rpm the motor is running at 80+.
Do you think a the test like this would be as accurate at a lower speed.? My brain tells me that a lower speed would then takeaway the "high speed" part of the high speed-test.

of course high speed suspension and gear train tests can only be done at the same high speed that the problem is manifesting itself.

Hey Unc & Tommy

Yes yes & yes..
It is the high RPM's you're looking for in a H-S test but all conditions do affect results..
I do think a High-spd test done at high speed is best cuz real world results are best under real world conditions..
And Yes UNc,,,,,, what fun is a High-spd test at Low spd,,,,,, jeeeeeze..!

I myself have done the "high-spd" test at lower speeds (with high R's) when it just wasn't practical or timely etc. and I was fine with what I observed because I simply wanted a ball-park read..

However remember,, there are Low-spd jets and/or maps (and throttle positions) to consider so a Low-Spd (slow-spd) test is valuable for running the slow (lower) thru town RPM's..

Of course you know that for the the Mik it is throttle position you're testing Not RPM's..

Frisco

Thanks, I guess it would be called a "high-rpm" test !! but real world conditions give the best real world results.

I just got back from a 50 mile blast down the road on th 06 ultra. in 5th gear 80 mph is 3200 rpm. I didnt check any other speeds or rpm's, just went cruizin' to the local H-D to get a new pair of boots.... gotta do my part to help thier ecomony. I ordered another pair for work. I could get Redwings, but that dont help out HD any. and I think the HD boots are just fine for work! Been wearing them for the last 3 years.

Hey Uncle, if we wanted to help HD AND ourselves maybe now would be a good time to buy some stock and wait 5 years. Yay? Nay?

Good idea, maybe some financial advisors would chime in. On second thought nix the FA people, we'll figure it out ourselves.
