I just got my silencers in yesterday and I'm supposed to get my pipes by saturday. My Q is which jet kit to get when its time. I looked on e-bay for the dyno kit, which is what Yamaha sells and there were stage 1, 2, 3. What the hell? All three said they were for moderately tuned bikes. All i'lll have are fatty pipes, turbine cores, k&n air filter and snorkel removed. Its 60 right now and gets to the high 90's, sometimes 100, in summer. What am i looking for? Thx for any help you can offer.
