im new to this blaster stuff and was wondering what size jet i should be running in my carb. i have a fatty pipe and a power core for the exhaust, a k&n filter with no cover on the box, its bored 60 over, running the stock carb with i dont know what jet in it. it runs great but didnt know if i could get a little more out of it. thanks!

linking maybe a 300 or so, best way is to do a plug chop

i say around 290 or 300. but like stated do a plug chop. if you dont know how to, there is a search bar on the top of the screen.

i'm running a 300 with an f7, open box, uni filter on my sons bike, the extra flow of the f7 over fmf may be equaled by the higher flowing k&n, so i'm gonna say 300 and under, i see alot of guys running fmf's listing 270
start big, work down and plug chop along the way

well i have fmf fatty a uni pod filter and 67mm piston and i am running a 280. allthough i cant do a chop cause i cant get my bike to open up in all the gears

im running 270 with fmf and no lid so with ur filter you should probably try a 280 or 290

I'm running a 260 with a full FMF system and a No Toil filter with the lid removed. Sea level and mid 80's where I'm at.
