I am actually posting this for a friend who is having troubles with his banshee. He keeps fouling plugs and it ends up running off of one cylinder all the time. While sitting there reving the engine it seems fine, but there is no power in the first 2 gears, until he winds out 3rd gear. He pulled the plugs out, there is little to no color on the base ring on the plug, the porcelain and the ground strap are like a shiny black, no soot, and completely black and shiny. He is currently running fmf fatty's, ported motor, no air box lid, with a K&N filter. We ride basically at sea level or just above . His jetting is currently at 280, stock needle middle position, 30 pilots, 1 1/2 out on the air/fuel screws. Does this sound right for jetting. Also before our last ride, he always runs 94 octane, but could only find 91, then put in some octane booster, not sure on what brand etc etc. Could this cause problems??? Thanks A Lot

TTT..their are other mods that i listed above that millhouse did not mention in his first post..

hey, millhouse..forgot to mention about your mild porting, and your head being shaved a tiny bit
