Jetting help fmf


BAMF87

Recommended Posts

I can't seem to get my banshee running right. It has fmf fattys, k&n filter with no air box at all, I'm runnin 27.5 pilots 310 mains air screws 2 turns out. Elevation is 2000-2500 temp now 50-60. Any help? Is has some low end box and mid range. Once I get 3/4 throttle it goes like it should.

mains seem pretty big for just fattys and a k&n that set up should run around a 270-280 main jet, what colour is your plug, if its a tan or brown your pretty close if its black your rich, also your needle should be on the second clip, i use to have the exact same set up as you but im around 400ft elavation

this is the same plug, its from the right side. I dont have pictures of left side because i broke it during the chop lol but the left side looked alomost perfect it was solid white with a small brown ring. also the right side smokes more than the left and that is the side these pics are from. Should i go down to 300 mains? or 290?

Ok I'll do that thx

My bike is pretty close to yours. I run a 30 pilot with 280 mains and a toomey needle in the middle.

I also run my premix at 32:1 (Castor 927)

leaning it out on the needle would be moving the clip up

 

If it doesn't clean up until the top your waaaaaay fat.
