after replacing my crank i rebuilt my engine with old bearings, bad idea. blew one apart and fucked my piston. led to me buying this fella. the piston i got has windows in the side, different than the stock piston that came with the kit, that one just has dimples. The windows provide more lubrication from the premix and my bike's running real good, better than it was before.
Side window guys
