Hey, I have the following topic. My Speedy 3 had a massive water loss in the cylinder. Quite a lot of white smoke from the exhaust w. d. ride. After that no more start and water in the combustion chamber. Now new cylinder + piston etc. installed, runs in the stand clean and quiet. Unfortunately the power/geychwindigkeit (as before) is much worse now. On the just 40km/h does not choke. The cylinder is equal to the old 49cc. Does it still have to run in? [From Motor-Talk au the topic ‘Speedfight 3 runs worse with new cylinder’.]
