hi i am a new banshee owner as i just picked it up last friday i have been racing 2-strokes for about 6 years now and my dad has a rz 350 so i know a decent amount about 2-strokes but cant figure this one out....first off il list what it has just so you know...it has fmf fattys with fmf silencers, t.o.r.s eliminators, no airbox with k@n pods....ok when i picked it up i got it home checked the coolant and there wasnt much in there so i filled it and it hasnt leaked a bit, i checked the gear oil and there wasnt much in there i rode it for probably an hour with no problems it ran GREAT.....tonight i drained the gear oil and put some new belray gear saver in fired it up ran good untill i got out on the road then started running like crap...would barly idle and i would have the rev the piss out of it to make it go then it started it shoot flames and backfire out of the left silencer i pulled it into the garage and checked the gear oil and it looked low....i cleaned the carbs thinking maybe they were dirty....they were spotless now i cant even get the thing to hit not even with carb cleaner i think it is burning gear oil and diluting the gas so much that it isnt firing maybe a bad crankcase seal? any help would be great......for the records it is about 33 degrees out and my main jet is a 340 and my piolt is a 25 if that matters thanks alot
