Good move on the V-twin kawasaki. I used to do lawncare in the summers for $$$ and one problem we used to have with the older single cylinder briggs motors, was splash lubrication which would be a problem working on that slope for any length of time. They may have gone to pressurized lubrication now, but either way the Kawi is the better motor. Looks like is works pretty good. How long did that take?
