Hello It took me 1.5 weeks ago to buy a Rex RS 450, because I was allowed to scrap my car and there is no new one in it. The scooter is quite ok, but somehow it is bad. Living on a mountain and I only come crawling up on one side with just 15 km/h. When I was overtaken by another 50 scooter quite easily, I thought it could not be right. Also the scooters I had in my youth did not have such problems with the mountain. The scooters were not hairy. ^^ I then looked at YT how I can see if the throttle is still in it and then looked at the cables. There was clearly what was done only I didn’t know what and which cable belonged to where. Can someone here perhaps help me and say what was botched there? And what else could it be that the scooter pulls so badly? Thanks P.S. also strangely I find that on the CDI with Edding 30km/h, he stands, but on the straight line (only if it doesn’t go minimally uphill xD) already drives its 45km/h.
