Mr. Joe Rossier

I'll start by saying my HMF Sport Series ran awsome jetted the way it is listed in my sig. I just made the switch to an RE pipe because I was bored...........and the Rossier is the best looking pipe IMO.

I did see the jetting specs on the RE website. Is it possible those specs are for the 06/07 39mm FCR's only, and not the 42mm carbs from the 04/05's?

With my porting, HotCam Stage 2, and airbox delete a 162 main jet just doesnt sound right.

Is anybody running a similar motor setup as me w/ a Rossier pipe. If so what jetting are you running?

Sorry for yet another jetting post.

162 does appear to be for the 06 (or FCR's)

A 180 main with a 50 pilot should be very close for you

I would expect the range to be from 172-185 depending on temp/altitude/humidity

im running pretty close to what you are running except my piston is a 13.1:1 wiseco and i still have my airbox but tiwht a k&n with no lid so we should be about the same and my main jet is a 175 with a 52 pilot jet
