Hello I'm Ben, I'm from Michigan the Lapeer area. Last year in September I got an 11 year old Sunny JL50QT-6A
(Jinlun JM Star Sunny 50 scooter,)
GY6, 139QMB 4-stroke engine, engine is 50cc bored out to 70cc so still legal under the 50cc laws, max MPH is roughly 45, gotten 60 on steep hill down.
Its the old style modeled after the Honda Shadow/Joker.
Manufactured by the Cixi Kingring motorcycle company according to Vin search. It only cost me $400. Runs great, and great gas mileage as far as I can tell.
It has a slight hack, last owner installed a power switch because the ignition doesn't function properly, still requires the key to be turned partially.
Only issue is the gas gauge isn't working and I'm not too keen on changing the module myself.
