My son has Orange Hammerhead 200. I am in search of a replacement engine. Can anyone ponit me in the right direction?

whats the matter with the engine? does it need rings?

Piston, Rings, Etc. Upper end. Bottom end? Dont know enough about it to rebuild it. I am told a 150 GT motor will not fit in it because of mounts?

I think it will fit, the 200 is just a model# tj used when they were trying to make a 200cc engine. was it just smoking alot or did it make a knocking sound?

Piston is scarred, cylinder wall scarred, wrist pin blue. Looks like it lost oil to upper end.

you could put a 155 kit on it if there is not any metal in the oil screen

How do I identify motor to order parts? Is there a model # stamped on motor some where.

there is a series of numbers on the lower left side of the case. it should be a standard gy6 with internal reverse

Heres What I found: TJPS On side of Case

These Numbers are on the bottom:

157QMJ
*07010062*

if there is not alot of metal in the oil then you could go with a 155 kit, new cylinder, piston, rings, pin and clips
