Strange Problem

[WS6Drop]

My banshee makes a sneezing sound out of both exhaust pipes when revved. Flames shot out of one of them. I have just rejetted and checked everything over. The bike has FMF fatties with sparkies, proflow adapter with filter and no lid, TORS removed. The jetting is 310 main, vitos needle third clip and pilots at 27.5. The elevations is ~1100ft.

check exhaust for leaks around the cylinders

i think your getin to much gas lore your needles all the way down so the sir clip is at the end of the needles

then find a flat streesh of road and on that road with your banshee go 1-6 gear wen you hit 6 kill your banshee and let it role to a stop the pull the plugs

look at the porslin in the center it shod be one brown color (if the plug is speckled(like pock a dot)that mens its to leen and you need to move your needle up one spot)if the plugs are brown that is good and it shod run beter

hope this helped you

:thumbsup:

It was stock before because I just put pipes and air filter assembly on and rejetted. I havent even rode it yet. I didnt want to do any damage without knowing whats going on.

better to be too rich then too lean.

I agree but I figured 310 for my mods was rich. Its only pipes, filter and no lid airbox.
