Hello dear community, I have the following problem with my 50’s scooter Motowell Magnet City 2 clocks. But before here a list of the things I have made on the scooter: Since the scooter was strangled after purchase over the throttle ring removed from the previous owner but I wanted to drive “legally”, I bought the ring and built it in. Unfortunately I broke the Variomatics during the installation and so I changed it immediately against a new one. The weights are the same. In addition, I had already installed a new air filter months ago before this repair, because the machine lost power from 30kmh and didn’t get more than 30kmh. I wanted to turn on the scooter even slower, as if it didn’t get air. After the air filter change everything went perfectly. Even after the installation of the new Variomatics and the throttle ring. The scooter relaxed its 55km. Now the problem: My scooter loses power again. But not so much As before the air filter change that it goes into the iron at 30kmh, but somehow more undefined. First it goes off from the stand super and gets well on its way. Hardly it is after three kilometers warm and there comes a little headwind, it starts to slow down with fully turned up gas. Then I go back with the gas it picks up again ride. On a medium-sized climb it does this already earlier or also with headwind. Then I always have to take some gas away and then k Is there any clue where I could look for? Thank you for your ideas LG Jack
