Time to do some bike maintenance. This is what happens when your countershaft seal fails on a Rotax 652:
Disgusting doesn’t cover it. Oil-soaked grime? Getting closer. Regardless, it’s quite interesting because my intake valves are pristine. Gorgeous. No buildup whatsoever. This is in start contrast to the time when the BMW dealer in Germany set the timing wrong and I ended up with a non-running motor thanks to the generous crusting on said intake valves. Speaking of valves, I dug in to check valve timing, which was spot-on. It’s never been out of spec. I think I’m moving to 15000km checks rather than the 10K recommended.
Oh, those ITBs? That ITB. It’s a Dellorto.
