Hello, the V-belt is huge with my scooter rex rs 450 and has now mounted a new one.. my scooter always drove 45kmh now he is driving around the 52kmh probably because the V-belt is a little bigger? because the old was torn down I could not take the measurements I ordered at ebay one that is suitable for the scooter but shouldn’t be bad anymore or? now the scooter does but at the start a bit funny noises that were not there before and that’s why I wanted to go after ask if everything is mounted correctly I have made some pictures vllt helps that yes. I guess it’s in such a part I don’t know how it’s called because I took photos.Do you have to hack the gears into each other? And then there’s another hose that was broken I think I glued it together again with armor tape is so right?Before it wasn’t together but it still worked but vllt it’s better if the line is on? many thanks in front of get out of here a video with the noise when starting vllt you can see what https://www.youtube.com/watch?v=-i9cX48m9JM&feature=youtu.be
