Hello my 50cc 2stroker with the mileage of 8000 has from yesterday to today many problems. It is from 2014 and is called “Speed Explorer” problems are the following: Motor strangles off when braking Motor strangles off when the horn turns turn signals Works perfectly at the beginning of the ride but after a short distance no more engine stutters Although the tank is full tank display sinks from inexplicable starting off although tank is full when you open the tank cover you see that it is up to the connection G is filled If you give gas, if only for a short time build up force on the rear wheel he stood a few days outside at about 3 degrees and rain could that be the reason? Battery was changed this summer These problems were however not present yesterday although he also stood there Tachowelle is also broken but that was already from purchase so Bin so grateful for any help.
