Richard, I have a hard time believing you would have cracked your crankcase with a metal bash plate. Zack is twice your size, and it took casing on a rock from 4 feet in the air. He's the only one I know so far to "achieve" that. I would check and see if the bolts are loose, but don't go nuts tightening them down. Once the bolt bottoms, maybe 1/16-1/8 turn is all it takes. I would also suspect the countershaft oil seal. This isn't that hard to change, nor very expensive. Does your bike steadily drip, or mostly when the motor runs?

I would be *very* surprised if you actually cracked anything. As Devon pointed out, it took all 240lbs of me, 4ft of air and a pile of rocks to land on to punch through the bash plate and crack my cases. There are so many bolts holding the case halves together that I couldn't imagine the cases moving on each other either... I assume that you've been paranoid about checking for leaks elsewhere, for instance my shift lever shaft seal is leaking and due to the lean of the bike, the oil runs down the cases and leaks off the drain plug. The only other thing that I can think of is that you've got the standard "short" bash plate (whomever at Utah Sport Cycle decided this was a good idea should be punished accordingly) that's cut for a centerstand. This leaves the very last bolt on the case vulnerable to rocks... I can't remember which bolt you said was leaking, but I suppose with the crappy short plate, it *is* entirely possible that a rock got up in there. I'd be more than happy to help you out with it in any way I can... I have got mucho experience with cracked cases> It's pretty clearly comming from the seam between the case halves.

Since the transmission fills much smoother. Here is my question...I rode it this morning for the first time on the freeway. When I got to work I looked on the left side of the bike (transmission) and observed some oil leaking from around the gear shift area of the case. Does anybody have any idea where I should begin inspection???? Thanks. > > Brian > 1990 KLr 650
