1994 Honda 4trax type2 200 cc. The plan was to rebuild the top end after running it out of oil (unfortunate oil leak) this winter. Quite a bit of smoke while it ran afterwards.

We have the cylinder out and there is a bit of light scratching on the bottom of the cylinder wall, and scuffing of the piston skirt. There seems to be no up and down play of the rod, but there is a bit of side to side play. While it was running, I didn’t really notice any obvious clunking.

-how much side play is acceptable? I was hoping to just have to rebuild the top end, but what is an indication for rod bearing replacement? And then, how much work is it to get the case split down to get to the crankshaft? Just trying to get a feel for what I’m getting myself into…and what generally needs to be redone while we’re in there.
