my rh rocket cover gasket leaked a bit before my tappet adjust and a lot more after. It is hard to get all of the old gasket off. There was small stubborn bit at the back that wouldn't come off to I rubbed the edges down and put the new one over the top. Whats the best way to get the last bit off without scratching ther metal? Some gasket removing chemical? The oempaper gaskets aren't very good, anyone tried gasket in a tube? Have stevio's gone to rubber reusable gaskets, sounds a good idea. Oh well another oreder for a dozen gaskets.
