oil in the exhaust

what would cause oil to pass thru the exhaust? The bike is a 77 Maxi Sport 1 speed. thanks Ray

Re: oil in the exhaust

I'm having the same problem with a 73 Ciao.. at random it will just kind pool up in the exhaust and i'll have to pull the bike back to dump it out .. it does it like once every 3 weeks.

youre running too rich probably. i would guess thats unburned fuel coming out and is black from the carbon. do a plug chop or just look at your plug, its probably black and nasty. -jason
