Yamaha Waverunner III 650 Engine Top-end Rebuild

This 1996 Yamaha Waverunner 3 650 engine needs a top-end rebuild. The rear cylinder had almost no compression and it turned out to be a ring busted on one of the pistons. The front cylinder also had a low 70PSI compression test. I ordered a top-end rebuild kit, honed the cylinders, reassembled the engine, and got it running! The next video will be rebuilding the carburetors and taking this thing out on the lake.
