Which Engine should I buy?

[wrice4]

Hey everyone, I am looking at replacing my QIYE 125cc engine on my mini chopper. This is just going to be a cheap replace because I do not ride my chopper that much. I found 2 motors.

Lifan 125cc or the Lifan 140cc

The 125 is $250 with free shipping
The 140 is $250 + $50 shipping

I have read negative things on the 140cc engine, but I have heard it is pretty powerful.

I have read amazing things about the yx140cc, but I am not really wanting to spend over $300.

I am wanting an engine that can get me up to about 50mph with out dumping money into it. Any suggestions?

go with the 140 for 50 dollars shipping it would be worth the extra power

I was just told by a lifan vender that the 140cc isnt anything better than the 125cc. Its a waste of money he said. He told me to ge a Honda CRF 50 motor and upgrade.

Keep away from china crap if you can help it.
That honda will be much better in the long run.

CRF 50 is a pretty small motor... For $250-300 couldnt u fix the one in the chopper?

The 50 is pretty small though, the lifan will run great if you treat it right. The only reason people would blow them up and say they are crap is if they didn't take care of the engine.

So i would go with the 125 lifan

That's what I'm wondering, unless there's a hole in the crankcase. Parts for the Chondas are generally pretty low.

Ya I decided to just keep my motor that's in it. Ported and polished carb and made jets bigger. Upgrading sprockets tomorrow. It's running like new again just taking it apart and cleaning it up.

Even so, I've seen some amazing things done with JB weld.
