Is it possible to use the OOR 250cc full engine kit on an Ace 50? It won't be legal, but do you think it would be possible in relation to the frame/electricals/mecanical?

I've e-mailed OOR and they think it's possible, but are not 100%

(I have their 72cc tune up kit, and I'm pleased with the top speed but need more power and acceleration)

Apart from engine mounts, there appears to be no difference between the 50cc and 125cc versions.

Perhaps a 50cc owner could confirm this.

Got a 50cc with a ohc 125cc. Had to build new mounting brackets in front of the engine. And cut down the link arm for the gear.

Sounds good Jorn. Is it the 125cc from an original Ace?

Have you got any good Pictures of the brackets and how you solved Everything?

No, its not a original ace engine (cg) with push rods. Its a zonghshen cb engine with overhead camshaft. Thinking about getting the 4 valve convention kit for it. But the top speed is quite ok now, so time will tell what i will do with it.
