Hello dear Schraubergemeinde So I own a Kymco Grand Dink 50 S 2 timer. Year 2006 ,15,500 km mileage …Renewed exhaust (original) clutch. Variomatics along with 8.5 gr. weights (which were previously also included) also original, carburetor (was set in workshop) Malossi cylinder and piston new candle.The problem is that as soon as he smells a mountain only drops from almost 65 km/h to 25 km/h. The speed of the engine then goes down and from 20 km/h he turns around wi cold start was also renewed as well as vacuum pump….What is that supposed to be so fucked up ???? On the mountain I have quite a few difficulties to keep track of the already heavy scooter since one is almost before the overturning….Bin with my Latin now really at the end…WEISS EVTL. JEMAND RAT….Dane in advance
