so: feracci pipes, k&n air filters, mikuni flatslide carbs. i synced carbs earlier this year, and never got around to rejetting (shoulda done it when i was in there...) but anyways, i can't remember what size main jets i have in there, but they're too big i'm assuming- it bogs if i whack the throttle..aside from that it's fine. should i just go maybe 2 steps down in size? any recommendations?
