Picked up a TW200 in a package deal. It needed work. I originally thought it'd be a simple piston ring replacement, but it ended up being a smoked crankshaft.
While apart, i blasted and powdercoated the cases. Bike is still being worked on, but engine runs well!
The porting made a noticeable difference in the high RPMs. Carb needs a rejet to get some low end throttle response back.
