I'm in the process of putting a new Hinson clutch basekt on my KX 250 and thus I had to remove the clutch cover. The clutch cover gasket adhered to the case soo tight, I had to bang it off with a rubber mallet. The remaining gasket is practially glued to the case and clutch cover. I've never seen a gasket stuck so tight to anything. Can you guys give me some suggestions (i.e. tips & tricks) to removing the gasket without destroying the mating surfaces or paint?
