I said it would not work with that frame. That's a pretty old engine, lot of changes since they built those, the GY6 and a rear wheel shaft, would never work. Any of this stuff needs to be modified, just keep moving forward. They use them in Quad ATV and Go Karts also.

I have a hp 170cc kit for the GY6 with high top piston, all the parts you need plus gaskets. You might look for a hp piston fror that engine. Wiseco can make you a custom piston for $90 or less. One of my HP engine has a teflon coated piston.
I would run that engine till it won't go anymore, then sell it on eBay as antique, lol.

Do not waste your time with a predator. I thought it looked like a two-stroke but the chain drive was throwing me off. Well now I know. See the measurements and if maybe you could find a cheap GY6 to throw in there. It should mount right up by the looks.

I honestly would try to get that two-stroke running but it’s not mine. I would try to modify the parts I needed with other parts that are readily available

There has got to be parts out there for something else that would work. For the cables, measure length, check the ends to match, etc. I have had to modify plenty of parts from other things to work on current projects because of unavailability or I didnt want to wait weeks for something.

I have a 150cc Scooter, the CVT trans has a shaft out the back of it which your rim and tire mount on. you have a chain drive to the rear wheel. Can you mod the trans to mount a rear chain from the shaft to turn you rear rim.
