Finally got the engine back in after replaceing the timing chain, the tensioner, and piston/cylinder. While I was in there I did the gear reduction, what a difference. I bought used parts on Ebay for $30.00. If you are using your Foreman mostly for mud and deep water I highly recommend doing this. It does cut into the topend speed but that doesn't matter to me. Can't wait to try it out, after some break in hours of course.
