Crank Bearing Failure – 2-Stroke Engine Carnage!

In this video, my 2-stroke engine suffered a catastrophic crank bearing failure that took me completely off the road. The bearings exploded inside the crankcase, sending metal through the engine and causing serious internal damage.
I strip the engine down to find out what went wrong, inspect the crankshaft, bearings, seals, and bottom end, and explain the signs of bearing failure in a 2-stroke engine. You’ll see the full teardown process, what parts were damaged, and what needs replacing to get this bike back on the road.
Then I walk through the repair process, including rebuilding the crank, replacing bearings and seals, cleaning out metal debris, and reassembling the engine step by step. If you’re into motorcycle mechanics, 2-stroke tuning, or DIY engine rebuilds, this video shows exactly what happens when a bottom end fails—and how to fix it.
