Hello together! have the following problem with my Peugeot kisbee 50 cc 4 clock .9000 km.bj 2013. Last time at the traffic light suddenly the scooter doesn’t drive anymore, engine runs. also takes gas but doesn’t go off, only after eternal time give gas he drives off quite slowly and then also maximum 20 kmh. if I let go of gas then dead again, about after 1 minute give gas he drives creeping again. I’ve already checked the following clutch disassembled: ok vario disassembled: ok converter : ok keilri emen ok but the width is 16 mm original 17,5 had opened the vario cover and let run, I have seen the strap does not rise high on the Vario page. can it actually be the strap is too narrow? what can that be. help am doubting.
