Engine differences
Hello Folks;
I have a 200CC ZHEJIANG X-MOTOS and I need valves. There appears to be several different types for sale on E-Bay and AliExpress, all with little differences in their specifications, my engine is a ZS169 FMM, where is the best place to get the right valves for it. I have already purchased a set on AliExpress but they are not quite right. Please advise Mike Coleman Ontario, Canada |

Send us a picture of the motor, I've got one that's marked ZS169FML, and it's actually a 163FML. Early on there were some, shall we say, "discrepancies" with how they were marked. Also, yours says, based on the FMM part, that it's a Chinese "250", which is marketing speak for 223-229cc. It could also be that it's a Yamaha clone, but we'd need to see pictures.

Wouldn't the 169 indicate a 68mm bore, thus making it larger than the 229cc 167's? If so, it is not a 200cc, but closer to a 250?
A ZS167FMM is a Zongshen CG250 engine, essentially. EDITED the model Displacement is 229cc with a 67mm bore. x-moto lists valves... https://www.motor-x.com/zawory-glowicy,c.html Though it is a long way from Tipperary when you consider shipping. If you read this post, you may want to measure bore & stroke before ordering anything from anywhere. Seems they will(did) mark them as having a larger bore than was actually the case. https://www.chinariders.net/showthread.php?t=17552 tom

Gents,
It is a 65.5 MM bore, I measured it and calculated the displacement at 230CC if my memory serves me. Franque, I agree on your discrepancies comment. I have been involved with engines, mechanics, motorcycles and engineering for over 60 years and I have never seen anything like this. The bike will be for my grandchildren to ride, so far I have stripped it to the bare frame for cleanup and repaint, changed all the bearings and now it is going back together. Thanks Mike Ontario, Canada |

Try looking for 165FMM valves. You might be able to get valves for a Hawk or a TBR7 that would work, but out of curiosity, what is the stud spacing on the head?

Franque,
Here is a picture of a head I found on AliExpress, if I cannot find the proper valves I will replace the entire head assembly. I have verified the dimensions shown, this head will fit my bike. Regards; Mike |

This listing(I searched for Lifan 200cc valves) may list some that would fit:

Order these, then cut the valve tulip diameter to the narrower dimension you need. Just need a lathe and some machine cutting bits... length is close enough on one you can grind/machine it a bit shorter.
