Oh No QJ 157qmj-3 anaomoly engine.

OK so I have called scrappy dogs and they have like zero parts for this scooter that aren't interchangeable from the regular 157qmj like the intake manifold for one.

I have no idea what other parts on this engine aren't interchangeable and I desperately need a new CLUTCH.

Do you guys think a regular 157qmj replacement clutch Will work?

Any information you guys can provide me on this particular generation engine I would be extremely grateful, the model of the bike is a '09 benello andretti xt by QJ MOTORS.

157qmj is the engine. The "-3" is part of the individual bike number.

Since it is a 157qmj, 157qmj parts should fit.

So further research says to use a gy6 250cc or Gy6-B clutch, and a standard 157 bell.

That's an anomaly variation of the gy6. It's difficult to find proper parts for it.

Yea blueboy this what I'm learning now.....
Anyway you could link me to the clutch that would work? I can just use the old bell housing I'm sure?

Thank you for taking the time to check on things for me, I'd be lost without you so far.

I could also upload photos of the clutch and take measurements is that would help?

Do you think it would be a better idea to just rebuild the stock clutch? I don't know what's wrong with it ATM but I plan on tearing into it tomorrow, it keeps jamming up and staying engaged, what could the be?

According to all my research, your bike uses the 250cc clutch.
