Just doing a bit of research into motors at the minute and I'm looking for feed back from guys that can compair both.

I've no experience with any lifan motors, but I like the idea of the oil filter on the 150.

Everyone and their mother seem to be specing the yx motors in bikes this weather, so I'm guessing there good as well.

The motor would more than lightly be running stock to start with.



Is there any major difference (realiability/power) or is it just a case of whichever you can lay your hands on at the right money???

I would go Lifan. Their faster then the yx's out of the box. Many people go the yx way cause you can put BBK's and stuff on it. But really your going to need a decomp cause if you kick it wrong once. It will break. Go lifan and have a reliable motor.

I have both motors. They both have proved to be pretty reliable and do a great job for what I do. The YX160 vibrates more and has a noisy top end compared to the Lifan. It's almost like the YX just isn't as balanced as the Lifan. As far as power goes, the Lifan feels that it has just as much displacement as the YX160. I have a feeling that when I upgrade the YX head to a V2 my opinion will slide more towards the YX but for now I'm enjoying the Lifan more... Hope that helps...

You'll find that the YX ISN'T properly balanced (balance factor wise) ... otherwise it'd feel smooth being a horizontal engine ... That's also most likely WHY they flog out the oil slingers and chatter the clutch rubbers to death ...

what do you mean by it will break because i just bought one
if you put a high compression piston or kit, the engine will run the risk of cracking the cases as you kick start the engine. I have 3 yx150s one with pumped up to 180cc and no split cases yet. However I have personally seen others cases cracked!!!
