Oil leak from RH crankcase cover

[Angerhouse]

Hi guys, I think I am leaking oil from my crankcase at the right hand side. It seems like the leak is caused by the poor state of these rubber bushings circled in green. Is it possible? I can't seem to find these bushings on BikeBandit, they aren't specified on any parts diagrams. Any recommendation is much appreciated.

Only recommendation I have is that you give us a clue what bike we are talking about.

78 gs400 ??? You sure it's not the cover gasket- it looks wimpy compared to mine.
kickstarter shaft has gasket (#13 on fiche), but that leak would be pretty obvious

I thought I had a sig.. it's a 78 GS400.

There was less leak when I was with my old gasket. I just installed this one, didn't really think much else about it because I had just bought it from Bike Bandit...

Those are seals, not bushings, and they will be in the fiches for the shafts, not the cover.

The crankshaft seal is on the crankshaft fiche -- #15 on the diagram. Make SURE you pay attention and install the new seal the correct way around. Consult your manual, and/or look for a teensy tiny arrow on the seal indicating which way the shaft will be spinning.

I believe the other seal is for the kickstarter shaft, so (surprise) it's on the kickstart fiche. #13 on the diagram.

Also, be aware that BikeBandit uses their own doofy part number obfuscation system intended solely to discourage comparisons that would expose their inflated parts prices.

I'd get a suzuki gasket and be real thorough removing any old gasket from mating surfaces. Check for warped cover- lay cover on piece of window glass and check flatness; doesn't have to be perfect,just close.

I think in the end, it was the crappy gasket. Although I replaced the seals too, I also got a new gasket that is much thicker. I'm a bit disappointed now I don't even drip a drop to mark my territory.

Thanks for all those who chimed in.
