650R woes that could have ended worse

check out my thread on advrider. Short story is the two 6mm bolts that hold the oil pump plate vibrated loose into the crankcase, got picked up by the tranny and trashed 5th gear, bent the mainshaft, and put some flat spots on the countershaft bearing, AND knocked a hole in the crankcase when it spit the bits out.




if you have a 650R you might think about spending the money on a right case cover gasket and loctiting those buggers. haven't been able to find anyone that has had this before.

I'm about to split my cases so will check this out. Thanks for the link to your topic over there.
