BAMF87 Posted December 19, 2011 Report Posted December 19, 2011 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. Quote
lt500rbigbore Posted December 19, 2011 Report Posted December 19, 2011 (edited) 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 Edited December 19, 2011 by lt500rbigbore Quote
BAMF87 Posted December 19, 2011 Author Report Posted December 19, 2011 I'm going to do a plug chop today. When I bought it it had a 290 main with airbox on and lid removed. I took the whole air box off and changed to a 310 main Quote
BAMF87 Posted December 19, 2011 Author Report Posted December 19, 2011 Also Santa is bringing me chariot reeds for Xmas so then what should I be at? Quote
Larry's Shee Posted December 19, 2011 Report Posted December 19, 2011 Try leaning needle, and see if they're stock needles. If they aren't stock, might try stock needles. Quote
BAMF87 Posted December 20, 2011 Author Report Posted December 20, 2011 Which direction on the needle is lean? I just did a plug chop I don't have pics but the left side seemed perfect with a light brown ring and he right side had a little darker brown but wasn't a perfect ring more like swirls. Quote
BAMF87 Posted December 20, 2011 Author Report Posted December 20, 2011 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? Quote
BAMF87 Posted December 20, 2011 Author Report Posted December 20, 2011 And I just moved the needle clips from 3rd slot from the top to second from top Quote
BAMF87 Posted December 20, 2011 Author Report Posted December 20, 2011 Yes I usually have to add trans fluid every other ride Quote
BAMF87 Posted December 20, 2011 Author Report Posted December 20, 2011 Ok so should I mess with jetting? Quote

Toybreaker Posted December 20, 2011 Report Posted December 20, 2011 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. Quote
Larry's Shee Posted December 20, 2011 Report Posted December 20, 2011 I'd do leakdown BEFORE you tear it down to be sure that's the problem Quote
