Motoseal 1 is the best case sealer available. Also known as Yamabond, and Hondaseal. Used by every bike shop for years. It seals any engine case with no worry of leaks or re-dos. Don’t spend alot of money purchasing engine case gaskets when Motoseal will seal just as well for much less money. For example, when installing the Balancer Lock (Doohickie) on a KLR, just rub a thin coating of Motoseal on the old gasket and bolt your engine back up. Even if the factory gasket is broke in a couple of places, no worries.
