I just recently traded for this China 4 wheeler, I have no idea what it is other than it's a GY6 150cc and says BMX on the cvt case and can't find anything on it on line. I'd like to replace the plastics on it but seems that I can't find any info about it how does one go about buy fenders and all for it?? Are they all interchangeable? Does one body kit fit all? Any help would be appreciated.
