Last weekend at the Devils head cross country race, I managed to crash and have a stick rip open the rubber half circle gasket on the head, subsequently spewing oil on my leg for over half the race. I am happy to report I ran over 45 hard/race miles and did not lose all that much oil. I drained the frame and came up with almost 800mls of oil. Service tech at Action Motorsports/Oregon city, said the frame holds approx. 950mls, and the likely hood of damage was nil, if I still had oil in the frame. Action Motorsports also did me a huge favor and had the new gasket and new clutch put in by Friday, with a Tuesday drop off. Great turn around, thumbs up to them.
