Buying a Seized Kawasaki GPZ 500S Ninja 500 Project Bike! | Part 4 - Bent Valves

Part 4 of the seized Kawasaki GPZ 500S / Ninja 500 rebuild. The head is off so I can see the damage properly. In this one I’m stripping the cylinder head and inspecting the valves after the engine locked up. The bike was dropped, then wouldn’t start. Now the valves are out and it’s clear some are bent — on this twin that usually means a piston kissed a valve. Possible causes I’m looking at: Watch Part 1, Part 2 and Part 3 on the channel. #ninja500 #ex500 #gpz500s #kawasaki #motorcycle #projectbike #enginebuild #bentvalves #cylinderhead
