Hey guys. I'm building a drift trike at the moment. Something to keep me busy during quarantine. I ordered a chinese 125cc from Amazon and when I got it, the engine had no compression. Tore it apart to find piston ring gaps were stacked on top of each other, valve lash was miles off, timing was off, and the cylinder was badly marred up. Nonetheless its scrapped. Any suggestions on a reputable website to purchase an engine?
