Mud and water in my engine :(

<< < (3/3)

If there was a little hiding in there and my bearings go early, the bearings are probably 10+ years old anyway so I wouldn't be losing much off their lives. The only reason I didn't have the bottom end done was I couldn't find a local shop to do it at a reasonable price. I don't have the work space or tools to tackle that job myself.

I have yet to compression test it BUT it feels too easy to kick to me. Before it hit the mud I had just torn it down, all looked good and and it read 165psi when I put it back together. Now though it "feels" easier to kick to me even though the piston, rings, and bore didn't look any different than when I tore it down before. There were no streaks from dirt etc... it was an even glaze all around. I lightly took that off with a scotch bright pad. I can kick it in tennis shoes without fear for my shins. It runs great, has good snap. I'm hoping when I compression test it, it will just turn out to be the result of my new walking regiment I've been on to get in shape. I was in pretty lousy shape a year ago.

Finally got around to compression testing it (has only had one 30 min test ride on it since going together). I musta been high with joy before or something. It made MORE compression (maybe new gaskets were thinner?). Before ripping the bottom of my shoe off it made 170+psi with a dead cold cylinder. I'm surprised it doesn't ping. Thank god they sell real 93 octane down here.
