How do I get to this leak?

[gcall07]

I have heard of old mechanics plugging up pcv and vacuum ports on automotive engines, rigging up a shop vac to the oil fill, and putting the crankcase into a vacuum. Then spraying off the leaking area (timing cover, lower intake valley, etc) with brake clean letting it get sucked in to clean oil residue away. Once clean, they would apply rtv or engine sealant to area, which would get sucked in also, then removing vacuum. I haven't seen it in practice but a co-worker of mine told me about this and says he has done this with success to a few engines. I'm not sure if this would work for your problem but if it doesn't then you just have to split the cases, same place you are in now.

Cool idea!

I wouldn't mind just wiping it down after a ride but when it drips, it's right on the exhaust and the smell is not acceptable.

Understood, plus your bike is really nice.

Dumb question....could you then remove the crankshaft ?

Not with the cam chain still attached.

I suppose if the cams were out, you pull the crank, rods, and pistons out from the bottom, but why? Sell parts on ebay maybe.

If you do split the cases ThreeBond 1211 is great case half sealant. About 20 bucks for a tube, lasts a long time.

Don't forget the bolt tightening sequence and the plates behind the clutch basket.

Might need a new oil pan gasket or crankshaft end seals.
