Can any one identify this mini chopper?

Its hard to tell... but off hand, its a chinese 49cc or one that had a honda ct70 type engine...

I think it had a gym. Look at the rear sprocket and it also appears to have a battery box. But I am no expert.

A GYM????

I'm not sure what type But to me looks as though someone beefed up the gooseneck area. I like that frame. I have an original 1960s easy rider chopper style mini bike frame/mini bike.

Thank you everyone do you think that is the correct sprocket? It's a 27 tooth with a 420 Chain im going with a 10 tooth clutch on a Predator engine

Going to need a much bigger sprocket than 27t...
Need at least a 50t... More like a 60t...

Thank you all for the reply so according to the Calculator found on this site with a 10 tooth clutch i can do 23 mph and a 12 tooth i can do 30 with a 60 tooth rear sprocket and 13 inc Diameter tire dose this sound right to you? im not a speed Demon

It's not about the speed so much it's the clutches ability to handle the load on it from the given ratio...
10 and 60 should be pretty good start.....
