Question New Cams

I was cruising sites looking for performance recommendations and I fell on what appears to be a great site called nightrider.com. They have a list of recommended perfomance mods that give decent gains without being over the top. The following link takes you to the page for their recommendations for a TC96:

http://www.nightrider.com/biketech/h...e_upgrades.htm

Since I'm not very tech savvy, I contacted them so they could dumb it down for me, and here's the text of their reply:

If you already have SE Race Tuner, you (or your tuner) already have a lot of control over the EFI system. The simplest thing for you to do is to go into the O2 Bias Table in SERT and change all the values to 750. This simple change will richen the fuel ratio while the EFI is in closed loop
(idle/cruising) to 14.2:1 from the stock 14.7:1 value. This is your biggest "bang for the buck" for your current engine mods.

The next thing I would do to the bike is simply install a mild bolt-in cam.
This is going to get you the biggest jump in power for a single upgrade. For most riders, there is no reason to go beyond this point for anything other than 'braggin' rights at the local watering hole. SE Race Tuner and a competent tuning should be able to tune your bike without any additional components.

Since you have SERT, using the O2 IED is really not a viable upgrade. The O2 IED is an 'electronic' version of setting the O2 Bias Table to 750. You can do that right now, so no reason to spend $50. The LC1 WBO2 upgrade is an elegant way to automatically have the bike tune itself while you ride in the closed loop (idle/cruise) mode. But installing the new performance cam would still require some fine tuning of the fuel map to handle heavy/full throttle operation. So I recommend having your cam installed and get the engine tuned by a competent shop. Most shops are very capable of setting the wide open throttle maps, but the idle/cruise map is very dependent upon the knowledge of the mechanic doing the tuning. If they don't tune the bike properly, adding the LC1's is a way to stop worrying about daily riding and having to take the bike for additional tuning.

I'd love to sell you the LC1 WBO2 upgrade right now, but from a 'cost effective' standpoint I've got to point you in the direction that gives you a good chance of saving money in the long run. The LC1's offer an elegant solution to high heat and tuning, and offer some very interesting additional tuning capabilities that are useful if you wanted to do your own tuning, but I figure if I can save you money now you'll remember me in the future or if you have a problem.


So here's my question for you all: Does this sound right? And if it does, which of the recommended bolt-on cams that they recommend can y'all recommend?

Andrews TW-26H
Crane HTC-300
Kuryakyn TC-1
Andrews TW-37H
Crane HTC-310
Andrews TW-44H
Crane HTC-316
Kuryakyn TC-2
Red Shift 575

I know this was a long one, but I really hope folks can take the time to read it and provide some feedback. Thanks in advance!

Default Pardon my ignorance

And part 2... How do I know that my local HD shop that's doing the tuning is competent enough to get the idle/cruise map right? Is there something on my dyno chart I can look at?

Default New Cams

All of the cams you listed are fine cams. Compare the specs and you will see they are all close in thier specifications. Generally the longer the duration the higher the compression ratio needed. Be honest about how you use your bike. You can achieve almost any horsepower you want, but if you build a drag race motor you will not be happy riding to work or on a tour. Conversly if you ride fast and hard on short runs only and don't care how reliable your bike is, or how easy it starts then build the hottest motor you can afford. Again, the operative phrase here is "Be honest with how you ride" Whatever you do, enjoy your project and have fun.

Thanks for the input. I don't need a drag racer. I use my bike for cruising and touring.
