I am haveing my motor done this week and was woundering if my jetting would be pretty close to what it is now with the mods i have listed below. i am having a wiseco 11:1 stock bore piston put in with a stage 2 hot cam right now i have 155 main jet and 40 pilot. do you think maybe i should go to a 42 pilot? I know right now it starts very hard inthe winter.

Do you get more power with same bore with a wiseco piston

It should give you more power, as long as it is a higher compression than stock, which is 9.2 to 1.

with the air box lid on in the winter, i run around a keihin 160 or so. i would run a 42 or 45 pilot jet. if it is hard to start, try pumping the gas a few times before you hit the start button.
