Long story short, at the end of last season I picked up a 99 136" Zrt with a 900 tripple motor with unknown miles. One cylinder had slightly less compression than the other two so I bought it with a top end refresh in mind. I pulled appart the top end a few days ago and half the studs and other fasteners were siezed and or stripped upon removal. All the pistons and rings were completely worn out, even the wrist pins were grooved and discolored. Upon further inspection the rod/crank bearings had worn and cracked needle cages. I decided to take out the motor and completley dissasemble it, which still hasnt happend becase one of the motor mounts has a rounded out allen/plowhead bolt preventing the crank case from being split. Anyway, when I flipped over the engine to remove the lower crank case bolts the first thing I saw was a ton of epoxy smeared on the very center of the bottom side of the case. I can only assume this was done to cover a split or cracked case....
Should I even consider trying to rebuild this thing, or start shopping for a lower mile replacement engine?
