Hi, I'm still kinda new to superjets and Yamaha based skis, but I'll say right now I'll take a yami over a kwaks any day! My question is thus, what jetting should I try for my 650 6m6 superjet? It has the following- wetjet kraze/ west coast pipe, Factory x girdled head 180/180, k and n air filter, mag pump, 13/18 impeller. I'm 145lbs. I want all around performance. Stock jetting is 120 pilot, 115 main I believe. Going to try 140 main, 135 pilot, and cut the pop off spring maybe just two coils down. Anybody agree?
