2 Strokes Down Under

thanks for replys everyone,

cheers Neil, learning the hard way apparently

Thanks for replying people, after some research on here, I'm assuming I have the seals in the right way, but they are "YAMBITS" seals, yes, anybody used crank seals from yambits , is this the reason gear oil is getting into crank , why they no good ?, please any contribution is appreciated...

hello all ive just rebuilt a 1983 rz350 ypvs

and it seems I have a leaking right hand crank seal, very frustrating , so my question ?

Is the right hand castellation crank seal suppose to go with castellations facing inwards, towards bearing or outwards

thank you for your help
