Did the top end, had the jug sleeved ect. ect. We originally took the bike apart to replace the base gasket then just ended up doing a top end anyways. If I hadn't seen the coolant at the base here, I never would of known. Im to the point where I might just get some copper sealer sealant and paste it on both sides of the gasket and see what happens. The bike rips with the new top end btw.
