Okay so now I have finished my 80cc (66cc) motorized bike. It goes badly on the higher laps. It does not want to rev up. So right now it is doing 34 km / h or 21 mph. Feels a little for that kit. But it does not go as it should at the high revs. Bought a carburetor like this (https://www.amazon.se/Alamor-Carb-f...0cc+66cc+80cc+förgasare&qid=1610143306&sr=8-2). Where can you buy carb jets for it? It gets too much gas!
