Hey guys I have the 66/80cc bikeberry engine with stock carb and expansion chamber. I’ve noticed that the engine seems to max out speed when I’m only at about 3/4 throttle and it will go about 25mph. Is this because I need to adjust the carb or is there another issue that I’m looking over. Any advice will help I’m still new in this hobby and I really respect all the feedback I get from you guys!
