Anybody have jet suggestions for a stock bore 250r with a fmf gold pipe and silencer, k&n filter open top air box, normal NY altittude??

jets and clip setting?

the bike wouldn't top out, it bogged down and fouled plugs so i went down 2 sizes on the main (not sure what it's at) and didnt fix anything....

help please!

I think the stock main was a 155-158 (someone correct me if i'm wrong) so i would think with those mods you should be looking at a low 160 jet. Just go to a parts center and pick up most of a few jets around that size, they're a couple bucks each.
