i just got my motor back in the shee thank god, anyway it started up right away and it seems lean at idle, i have to barely hold the choke to make it idle. is this because its new, or because i have the timing at 4-5 now? the only thing that changed durring rebuild was the timing plate, its got fmf high rev pipes, toomy 2 into 1 filter (no box), no tors, other than that its stock. the jetting is, 280 mains, stock pilot,middle clip at 600 feet above and 80* does this sound right? it ran good before. any info would be sweet
