Oily flywheel

[korned]

hey there

I removed my flywheel cover last night to remove flywheel and get lightened, inside the casing I noticed a consistant amount of oily residue .. is this common? or is this a problem?

could be a leaky crank seal? any hint of gas?

hmm i dont think so... seems almost straight oil

I would bet its a crank seal I had the same thing happen to two of my skis before.

Definatly a leaking crank seal. The only lube that should be present is a small amount of grease on the nose and the rear of the bendix. If seals are not changed soon you will eventually damage the front main crankshaft bearing from the air leak.

in a nut shell:

splitting the case without removing topend (pistons even height)...change one seal in front, two in the rear with grease added where the seals ride on the crank....clean up both surfaces good with razor blade and lacquer thinner carefully avoiding too much debris into topend....seal case back with yamabond or threebond 1211 before bolting back up....
