I just bolted mine on and pulled the rope. You can cut your fuel back a little, not mandatory. Engine is nice and crisp. I put the head on and a speedwerx pipe and left my jetting alone, I figured one off-set the other. Runs very strong.
what sled do you have? And what jets are you running. I have and slp single pipe, boyesen reeds, k&n filters. I was running stock 360 jets but with pipe I jumped up to 390's to be safe, is running pretty fat, do your plugs and pistons look good with the jets you are running and at what elevation, i rode yesterday at about 6500'. thanks
I run slp single, v-force reeds, k@n, 1/2 inch reed spacers, and the thing . have a set of rkt heads with 13.5 to one compression ride 4500 to 6200 and run 380's plugs look good and it runs crisp. could possible drop to 370's Right now im 1250 to 1300 on the egts
