I'm willing to bet it's not the header flange gasket. Your pipe is just all bent to hell and you're probably running rich as shit, it doesn't seat right like how you said and it's just spraying spooge right out of the gap. And that dent is ruining your scavenging which is the whole point of the expansion chamber and is also causing this because the gases (and oil that shouldn't be there) cannot escape. I bet that silencer packing is all but burned out or saturated with the same oily mess.

@StreetFighter85 Thanks for the tips, the only thing i know about the richness is that the guy said to run 34:1, and he said that there was a problem at some point (3 years ago) where it was fouling the shit out of the plugs. I'm looking into a new pipe, or a better used one, and going to repack my thingy, once i can get the darned thing off....

@apricotsnms516 fix the pipe situation, then pick a premix ratio. I run ~36:1 and then jet the bike correctly for that mixture. If everything is right there should be little to no smoke or spooge.

Left you a comment on Thumpertalk. Pacific pipe repair, high temp RTV silicone sealant, repack silencer, ratio rite, tune, go from there.

@apricotsnms516 dont ride it on the crap oil because if the crankshaft burns out trust me its gonna be expansive

[apricotsnms516]

@warezvz Well, the problem with that oil is I can't get it anywhere locally, so it adds an extra $5 for shipping.. and I'm already low on money as it is, that's why I got crap oil this last time. and yes you HAVE to loctite the screws in!! learned that the hard way! lost my mud guard lol... and again, i'll get the piston when it comes time, but i really don't have an extra $125 sitting around haha which is about two weeks pay.

@apricotsnms516 dude thats a 2 stroke enduro engine it will seize and take hevy damage if you put shit in it. Get propper oil like motul 710, 800 or repsol competition put atleast 2.5-3% if you mix it manualy. Your spark plug should be the color of dry coffe powder after you run it full trottle. The unscrewing screws is the problem that i told you about get loctite cream and cream them before you screw them in. Also change the piston rings they dont cost much but its good to change them.
