Shifter seal oil leak
 

Hello all,

Long time viewer new poster. My M has developed an oil leak at the shifter gasket and like most, every problem is corrected quick or my bike is parked!

I've read the manual page by page and it has no mention of that particular gasket. Just wanted to see if anyone else has had to replace the gasket and if there were any hidden surprises. I do ALL of the wrenching myself with the exception of the shaft drive and drum brake as they just intimidate me. Thanks for the help in advance.
