Hello,
As part of my preparations for this years Gotland Grand National, I did a quick service on my 2015 EC200. Air filter, front sprocket, gearbox oil, fixed the heated grips etc.
My bike has done approx 460 hours. I plan to do a top-end service when I get back from Gotland. I think its 130-150 hours since my last piston change.
One thing caught my attension: The gearbox oil had an unfamiliar smell. Since I'm no wine connoisseur, I'm not trained in describing different smells, but my first idea was exhaust or burned two-stroke oil. There was also a surprising amount of thick deposits at the drain plug, but no metal chips at the magnet.
I don't have time to do anything more before leaving for GGN on Wednesday morning, so I'll do the 3 hour race with the bike as it is. Then I plan to dump the oil again, and do the same test with my nose. If it still smells iffy, what do I then do? I guess a leaking exhaust valve could make a passage for the exhaust gasses into the gearbox (through the exhaust valve control rod aperture) ? I can of course service the exhaust valve as a part of the top end service. I did so last time, but would be surprised if it had started leaking after such a "short" interval.
Any other thoughts on this matter?
