Hi, I throttled my scooter again and installed a 50cc cylinder from Naraku, the standard exhaust, a D-RIng and again from 85 to 74. Roller runs super OUT of the car you drive longer full-gas 1-2km or even a little longer and you get a clamp! It goes out and you notice the wheel runs hard! After it goes on again immediately.. Compression 6 bar and candle is deer brown.. Can someone help me 🙁 funny this happens only at high speeds!
