I'm not sure which section this should be posted in but here is as good as anywhere.
I replaced the crank seals on my race bike "Blue Meanie" (MDS with 200cc Villiers kart engine) and have done about 6 sprint meetings since. Today at Houghton Tower, at the end of the second practice run it died then picked up again. After the first race run it died when I was slowing down and refused to start again. It has spit the cork gasket out from behind the clutch case and the gasket between the inner and outer clutch case.
I guess the crank seal has gone again, pressurising the clutch case.
I think I may need a different material for the seals. the methanol fuel must be attacking them. What is the best material?
I should really have changed them every winter
