Please some one if you can help I would greatly appreciate it. I just bought a 2077 CF MOTO 250cc. The first day I rode it the muffler came off! I fixed that but now there is a bad exhaust leak. I need to fix this, along with my next failed ride. I was driving home from work and it wanted to shut off on me. I eased it home only to find that the carburator wasleaking fuel from the side. I am not a mechanic but I really do not think that it should do the when that happens it bogs down it will not go over 50 mph now. I do not know what to do. If anyone can hep Please do so. Thank you very much
