sweetshee4312 Posted November 17, 2004 Report Share Posted November 17, 2004 Well im running uni foam air filter, with fattys, and trail ported engine....Im running 330 mains 27.5 pilots, and middle neadle, at 1000ft, I was riding the other day, on the road for a long streach, and i wanted to do a plug cheak and i noticed that the plug looked dry, like a white dryish, and the other side looks like the same, alil oily though....Im running yammalub 32:1 on 94, so i dunno why it looks like that....i dont wanna fry my engine, sometimes my engine will back fire.....but then after it warms up it wount...also it always cuts out in the air when its warming up, but then stops, and when i started out this day, i warmed it up, and ride it downt he road, and it just shut off for a good, 5 or 10 seconds, and wouldnt go, then it just turned on....whats going on hurr?

FIRST BANSHEE Posted November 17, 2004 Report Share Posted November 17, 2004 sounds like it's lean, backfiring is usually a lean condition, white plugs lean condition. oily plug on the right side could be a crank seal. check for air leaks and jet up 2 sizes and see how it runs.

fixitrod Posted November 17, 2004 Report Share Posted November 17, 2004 I ran 360's to 390's with my fatty's on a mild ported engine depending on temp. Needle dropped down 1 notch lean from stock. I'm at 700 ft in Indiana. Quote Link to comment Share on other sites More sharing options...
