Anyone know what oil seals on a 1985 lt250r would allow oil into the cylinder to be burned. I put a new one in for the crankshaft and it runs a lot less rich but my plug still fouls up and my transmission oil still becomes gassy and black when its supposed to be red.

 

Crank seals. You could do a leak down test on it to check the crank seals

 

Thats the only one? So that's the seal behind the kick starter gear?

 

It's the seal where the crankshaft comes through the case into the trans. On a 2 stroke the transmission and the crankcase are 2 separate compartments.

 

Sounds like i have to take it way more apart..

 

would a picture of the transmission help?
