    Been on ebay. Thire is only 1 jonway engine on thire. But no guarantee it works as sold as spares or repair. And I don't no what other chinese engine will fit. All I want is a running engine. That will go in the bike. And don't want to spent silly money on a new one

    It's a pretty generic motor
    Only some have bigger wheels.
    What's wrong with yours?

    Ok sounds like a fuel issue.
    And maybe the cam chain...
    But yeah I understand you.
    Peugeot v clic uses the same engine I think. It's honestly a really common 4t motor.

    I don't really want to touch this engine anymore iv put to much money into it. I really want to just buy a running engine. And bop it in. Job done. Started the bike today fires right up clunking sound has gone but half throttle starts to bog. So you got to come back off the throttle if you can get it to full rev. It judders and don't. Move when you sit on it.

    Sounds definitely like a fuel issue. The knocking could be pre ignition

    That's what it is called the flywheel was bouncing around. Tryed pulling it off but no luck. So will try tomorrow. So is that why it's hard to start now as timeing is off as I just tightened the nut back up. As I no it needs to be tdc
