Hello my name is Vlad im fairly new at these chinese motorized bikes got my first 1 about a year ago, im curently on my 4th and each one getting better by the day. I wanna try out a shifter kit with a 80cc preferably a ch80(wondering if anyone has any reviews about that engine) and a shiftet kit from SBP, i was wondering if anyone on this site has tried any of those and if so if you could give me some feedback on them as it will be a litle pricey
