Probably not. A 200 piston would have a LOT of clearance.ThysW said:I sent my barrel and old piston to ns two stroke so they can renikkel the barrel and supply me with a new piston. They redone the barrel and supplied me with a piston, but the piston sticks out about 5mm above the barrel. Can it be that they give me a KDX 200 piston. And yes they thew the old one away before I picked up there are a mistake.
