Our Trailmaster MB200 mini bike has hundreds of miles and hundreds of hours on its modified high performance Jiang Dong 196cc OHV engine, and we just broke it's crankshaft in half! In today's episode we completely disassemble the engine, give the block a deep clean, and replace the crankshaft, install a Fire 265 camshaft, add a new rod as well as other bits and pieces. This was not a comprehensive engine rebuild we should have torn down the engine BEFORE ordering parts, or just bought a new engine to start from. This engine has been abused over the years ridden hard and occasionally stored in rainy areas.

Thanks for Watching!
