I scored a set of new SE cams off of CL for a great price. Going to pick them up this afternoon. They are the .551 cams (p/n 25197-04). I'm not sure when I'm going to install them. I guess it largely depends on how long the bike will be down. I'm fairly competent with a wrench and am willing to try my hand at pretty much anything.

Does the service manual cover cam installs? I have a service manual in the mail on it's way to me as I type this. If not, any online resources that document the swap?

Additionally, I'm looking for an after market ignition module. Even though I scored the cams for a great price, I'm still working under the constraints of a tight budget. The TC88A is a little pricey. I'm assuming the SE ignition module will do the trick but, unless I'm missing it, the 2009 SE catalog only lists a module for 04-06 touring models. My Google-Fu has been weak trying to locate a SE module for my 06 XL. Is there a SE module available for my bike? Any other modules you guys can recommend that may be a bit more budget friendly than the Daytona?

What else needs to be done with the cam swap? Carb re-jet? I'm currently at 45 & 180. I suppose putting the bike on a dyno would probably be a good idea but, again, bike funds are limited.

And, finally, with the addition of the .551 cams and new ignition, would 80whp be a reasonable expectation? If not, what would be?

 

Dana(sp) makes a nice one, single fire, programmable too.

 

There is an SE ignition module for the 04-06 Sporties, but it doesn't really do squat other than raise the rev limiter. That's not really a good idea unless your going with lighter weight pistons.

 

Not sure, but the .551 lift cams may require new valve springs as well. Double check with a dealer's listing for the cams to double check wether new springs are required for those cams. As for the carb, your current jets are most likely just fine, get the cams in first and run the bike a number of miles and see. The tricky part when doing cams and ignition is, you need to remember that having your timing set properly is key to tuning your carb. If your timing is out, you can get false signs of rich or lean conditions that may actually be related to the timing and not an issue with the carb.

 

My suggestion is if you are doing cams, port and polish the heads and install some larger valves. then go do the dyno. The heads will make a much larger difference than the cams and you can find a local indy or machine shop that will do the job fairly cheap

 

Thanks for the input folks. The .551 cams are supposed to be bolt-in, no other valve train work required. As far as the ignition, I may just bite the bullet and go with the Daytona unit. However, with all of this considered, I may just try and find a good local indy and let him do his thing.

 

I doubt you will see 80HP with no head work. I'd sell the cams and do some head work, you have a perfectly good set of cams already.
