I'm going with S&S Power Tune Duals. The tech loves them because of fit and finish and they are easy to install. The tuner loves them because of the 12 and 18mm bungs on each pipe. Perfect setup for their DYNO.

 

don't know anything about them but as long as they like and recommend them you should be fine.

Not sure what tuning device you're set to use also but if you are given a choice between the HD street tuner and the HD SEPST, go with the SEPST this way you can tune your own bike (or have someone other than dealer tune it) later on if you change things up

 

per the SE catalog SE 254e are "race only"

SEPST is my choice as well as the dealers.

 

+1 if you are going to use the HD Tuner use the SEPST I would not even waste the $ on the Street Tuner, it is way to limited in what it will do and you will still be very lean and possible have heat issues.

 

Of the SE cams the SE204 would give you good performance that you would be pretty happy with. Average numbers would be low 90s for hp and low 100s for tq with a good intake and exhaust.

BTW the SE204s sound fantastic.

Good luck.

 

According to some of the BS about warranty that some have stated in this thread the SEPST should void the warranty as well because its "For Race Application Only". But we all know it won't. Just as the dealers and MOCO know aftermarket cams won't void your warranty either. It's pure propaganda to push their branded parts on you. Scare tactic......plain and simple.

 

grab some wrenches, and the service manual and install the cams you want in your bike. Take the money you save and pay for a dyno tune. win-win

If you're stuck with SE cams, the 204s are a natural drop in for the 103 motors, and work as well as a lot of aftermarket cams.

 

It absolutely will if the dealer decides not to cover it.

Good luck with that though.

 

one thing to consider. your factory warranty runs for 2 years. the magnusson moss warranty act covers that. when your factory warranty expires, and you are being covered under the esp, then all bets are off. it is not a warranty, it is a service plan, aka an insurance policy and they can deny coverage for whatever reason floats their boat and mag-moss won't mean a hill of beans then.
