Default YFZ450 Jetting W/FMF Pipe
What jet should I be using on a YFZ450, w/FMF Pipe, and K&N Airfilter? It's pretty cold here, about 35-40 degress. What about summer 80-90 Degrees? I'm in Indiana. Thanks!

What FMF pipe are you running? I run a FMF Titanium pipe and header on my 426 and have been very happy but I haven't seen much feedback. I just got my yzf450 and cant decide what I want to run.
