Hello, I have recently had a problem with my Speedfight 2: -all original except the optics -original exhaust, completely rusted & doesn’t sound so fresh anymore -gas slide throttle & distance ring removed -> runs 62 kmh -new spark plug -no longer reasonably tuned, because my father has twisted the screws (stand gas and the screw next to it) and we don’t know exactly how to adjust the optimal -gasifier is usually still clean So now to my P roblem.. I drove about 20+ kilometers yesterday and then wanted to go home, until my scooter drove only 50 kmh and then slowed down after a few seconds. Then the scooter drove only about 25 and made very funny noises. Out and turn on didn’t help anything. After my father had turned around the screws, the scooter drove probably more rationally. Now it doesn’t pull right anymore and even despite giving full gas only at 50 kmh. He needs to get out of the stand. also a certain time until he gets faster and then at 20 kmh he drives so 10 seconds, until then he gets faster to 50. I have no idea what that can be, but know me relatively well and that as a girl. Please now for solution suggestions 🙂 Thank you in advance!
