Cam timing problem

Not all GY6 cylinders are the same
Something to watch out for is that different OEMs use different patterns. Many OEMs are now using brand specific patters and in the USA there has a been a rush to call everything GY6 a generic part, THEY ARE NOT. Xinguye Linhai ZMD ZNEN QJ - VENTO all use different GY6 patters sometimes the same OEM like ZNEN will buy cylinders from three different factories meaning not all their 150cc units use the same engine parts. MRP now carries TNG scooter parts and the TNG parts are not all the same some are from CF-MOTO, QJ, ZNEN these are all different bolt patterns so DEALERS BEWARE when you buy from sources that don't know all the factories this is what you will face.
