Bike: 1978 or 79 Motobecane 50v
The bike is real slow and the engine sounds like its being restricted or bogging down. Last time i checked the variator was moving in and out like it should but i might be wrong. Also, the engine doesnt flex toward the back of the bike like it should. The belt was horribly worn and loose so i figgured that was the problem. I replaced the belt with a new one i got off ebay but the problem wasnt fixed. Now i think the problem is with the engine not flexing. Please someone help, i have been working on this thing for months. PLEEEASE.
