Blown gas quad engine

I have a 40cc crap chinese quad from Amazon with a blown engine.
Looking for any advice on what engine, torque converter etc would be best to replace.

Looking for a huge project but have welder and fabrication capability.

Seems like maybe a 49cc flying horse engine could work.
Any suggestions appreciated u

Depend on what route you want to go(also what is the intended purpose of the machine)...

Overall need to consider the compatibility of chains between them...
Those cheap 2 strokes, typically have 219 chain. So that has to be in factor when upgrading the motor, Youll need to get bigger chain and sprockets, but that will affect the gear ratio.
You can buy 219 clutches but they are typically really expensive....
