Delurk. I thought I'd gotten the dreaded shifter seal leak, then I cleaned up all the chain lube scunge from the swing arm and front sprocket. Lo and behold, no more "leak". (YMMV). As for MC oil, yeah, I buy it. Maybe I'm a rube, but if the MCN Downtime Files recommend it (and splain why), I'll go along! -Chris CB NYC 95 GPZ
