ZS-125 Engine replacement?

[Culley_Bristol]

Hi guys,

Im thinking about swapping my standard 125cc Honda CG clone engine from my Lexmoto/Zongshen Arizona for something like a 200/250.

Are there any engines out there that will slot right in without any major mods/swearing?

What about the CG250 lump? Will that pop straight in?

Thanks in advance chaps.

Culley..

I sort of doubt it. Even if it was possible I think if would be a lot less time and effort to just get a 250cc or so bike.

I would think if your 125 is a vertical engine, and not a hroizontal like the 110 derived engines a 200 would bolt right up...

I believe that a CG200 or CG230 (there really is not 250) would fall into place. The reason is that both of those motors are derived from the CG125, and I would guess that they're all identical externally.

[Weldangrind]

If you have specific CG200 measurements that you need, just let me know.

Thanks for your replies chaps.

Yeah i meant 230
Do you have a link/full spec sheet for the CG200?

Cheers..

yeah i agree with weldangrind. but the space for the bigger carbie needs to be measured between the head and the monoshock (?), tank and seat. i don t know what the zong 125 frame is like.

Its a twin shock bud. Should be plenty of room.

i've got a cg230 tell me what measurements you need and ill go get a tape measure out just let me know if you need metric or imperial measurements

[zingshoen]

dual shockies no worries. the carbie if you think 26mm mikuni, is higher too, where does your throttle cable run?

The bike in the pic has a counter-balanced motor, and most CG200 / 230 engines do not. Your 125 motor might actually be longer than a 200 / 230, and it might take some minor custom mount work on the front.

[Culley_Bristol]

Whats the difference between a counter-balanced engine and a non counterbalanced?

Sorry im pretty new to the world of bikes.

[Weldangrind]

A counter-balanced engine has a tiny shaft at the front of the engine that resembles a crankshaft, and it provides (somewhat) opposing forces to the crankshaft. It's the finned portion at the front of your engine.
