I’ve been dealing with this issue for a while and thought I finally had it whipped. I have a leak behind the transmission gear attached to the chain that sprays everything in oil. I replaced the seal, the spacer bushing bec it was worn, the seal, the gasket, as well as the sproket...
I bought a broken KTM last year to rebuilt and i did a leak down test yesterday and I have alot of air going out of my carburetor. I dont have a clue what is wrong with it.
My piston was TDC.
Thanks guys. Il
