MISCELLANEOUS INFORMATION ABOUT YOUR BIKE’S JETTING SETUP:

installed jet kit with 98 main with areap exhaust and stock intake and 2 washers above E clip, pulled good throughout the rpm range. Installed pod filters with stock runners and crankcase breather, started with a 104 main and stock pilot. Wouldn't start without choke when cold, low end was lean and pulled ok from 6k to 8k then leaned out till redline. Jumped straight to a 108 main and reset idle mixture screws 2 1/2 turns, low end still lean, idled erratically, slight pop on decel, after 8k pulled great. Installed 40 pilots and put one washer under E clip in third position. Still needs choke to start, idle is a little off, pulls pretty evenly from around 4k till redline. Synced carb, idles a little better but still off, can't seem to get it "dialed in" right.

took it to a dyno day to see where its at, 30.8 hp, seems pretty good, going to fiddle with the mixture screws to see if I can make the low end better, if not, it'll stay as it is.
