The top end is modified with a 70mm BBK, and other go fast goodies from SX Parts. The bottom end is completely stock (including the clutch). I would say it literally doubled the power output of this bike. Only time will tell if it holds up or not. I figure the clutch will be the first thing to fail, but who knows... I purchased most of these parts used from @DustySteelGarage who is currently building a 300cc XR150L engine, so check out his channel if that interests you.
