Good evening, I have the following problem with my Piaagio TPH C48 50 ccm. Since this morning my scooter does not accelerate as usual. The following has to be mentioned, my scooter was only throttled, everything else remained in serial condition. Until yesterday he reached the max. speed of 65 km/h at 8000 rpm. This morning, he came with trouble and distress, at 45-50 km/h at 7200-7500 rpm. By the way, one hears a metallic side noise from the Variomatics. (The Variomatics, as well as the e fixing screw has already been checked, it doesn’t seem to be there). Add to it that you do not hear this noise in the stationary gas, also noticeable that in the stationary gas the rear wheel no longer rotates. (In the mounted condition). In the last four days, always at the start of the engine in cold condition, a squeaking noise was to be heard briefly, for about a minute. Can someone help me further. The total running power is just 8300 km.
