Testing and sourcing parts for the Chinese scooters is not my primary occupation. This is more hobby than business for me, and I do this so that there is a place that other scooter owners can get information on parts before they plunk down their money without knowing what they are getting. I test virtually all parts I offer to make sure they fit and function, as well as being a worthwhile investment for the scooter owner. If a part requires fitting, you will probably find an article on "how to" on my Scooter Information page.This is only a very small list of the items my suppliers offer. If there are items you'd like to get information on, I'll be happy to attempt to get it for you. I'll be adding parts as items are tested and become available, so stop in often. I try very hard to keep all parts in stock, and the in stock status is updated daily. All restock dates are estimates, and can change, but I update them as information becomes available. I do not warranty any of these parts whatsoever and they come only with their manufacturers warranty if applicable and they should be professionally installed. I accept non electrical part returns within 30 days if the part has not been installed and is in clean, unused condition in original package. Questions?
