jetting issue

[LONGROD]

ok so My shee i got from a buddy will start choke out and throttle half in. runs like ass back fires, spits barely will run with clutch disengaged , then will rip on the main jet and the needle once it gets the fuel flowing.. it will not idle.. so went from 25 to 30 pilots because its what I had.. runs better, no spiting but little response until u run it on the main jet to clean it out. then runs strong on needle and main jet.. so I pick up some 27.5 pilots . and runs like shit, spits and back fires and hard starting..

 

 

stock motor except for fmf fatty's, tors removal, and open k&n filters

Try with cleaning carbs one at a time , reinstall choke tube.

fattys like big pilots my experiance with those is 280-290 main jet 30 pilot, stock needle all the way rich Clip all the way toward pointy end

tried that jetting set up not that needle position and it is way to rich on the bottom just blows smoke.. carbs r way clean and i added a fuel filter. could low compression make it run like crap with the proper jets in it.

and the previous owner ran it for years with same set up with 25 pilots and 250 main jets

Uhmmm, yeah. What is your compression?

 

Did you just add those fattys and filters?
