[QUOTE="sr5bidder, post: 1381979, member: 98736"] it is ..isn't it! the whole thing that brought this up is the 2nd post in a few days that has said that leaner jetting was required to get a fresh top end to perform..and in colder weather?? .my thought is a new top end has better compression than what was performing well before the rebuid so the new top end should be able to compress the mix to a higher pressure and burn it better..........I'm lost mine did great on the new top end and same jets and the reports are JD going down from 155 to 150 and motobk being at 145 going down to 142....but thats a 220 so I dont know... I am at 45/2nd from top/155 boysen 607 and fmf woods pipe I guess I should be glad my bike didn't require any messing around with jets....I do admit I droped the needle after the rebuild, though I could have tried the needle before but never did.
