Ok, I posted this under the forum of the Chinese experts and no one offered a reply so I am posting it here hopefully under the Chinese brands and someone will have an answer .
On a V-Bike with a 300 cc Loncins engine, does anyone know what oil filter will interchange with the factory filter ? Or, how to go about getting a OEM replacement

 

call these folks. they may help you. look for their 1800 number in the top left hand corner of the page. good luck. sorry i couldn't help more.
