Default Re: I need your guys' 2 cents on durability/ longevity issues on HT motors and.....

I would upgrade the crankshaft bearings to the type with a seal or shield on one side. 6202-RS or 6202-Z. The open end would face into the engine to get lubrication and cooling from the fuel-oil mix, and the other end would face towards the outside to give a helping hand to the external rubber seal to help seal the engine from air leaks.
