I've been away from the motorized bicycle scene for a while and was wondering who makes what's considered by most of you to be the best 66cc 2 stroke motor kits out there? Is the flying horse angle fire motor respectable? I know they all come from China, and that some are better quality than others. I would like to order a kit from a company who will also give me some product support if need be. I would appreciate any input. Thanks.
