Can you name this engine?

Fletchman919 · 03-13-2022, 10:52 PM

I bought this engine today for a minibike project. I was told that it is a 150cc, but someone else said it may be a 200cc. I can't figure it out, so I'm hoping someone can help identify it for me. Are there any numbers that I can look for?

Somewhere on the bottom sides of the engine will be an engine code stamped into the housing (example: ZS167FMM) That code can tell us what the engine size should be.
I say "should be" because sometimes they don't always get put together with the right bore pistons. More than one example floating around of a 230cc engine with a 200cc engine's bore size. etc.

Thank you so much! I will look for that and post what I find.

Looks to be a Zongshen (ZS) CG250 (229cc) pushrod OHV. 1 cylinder 67mm bore

Quite a displacement bump from 150cc.

I'm having a difficult time trying to post a picture, but the code stamped on the engine is 162FMJ and 86801617 which I imagine is a serial #. There's also a sticker with JJ0002, 86801617 and 20060824. Hope this can help identify it and thank you again for the help!

Lol! That is quite a bit more engine than I was expecting. If this is true, I may need to find another bike too put this on. Thank you!

a 162 is 1 cylinder nominal 62mm bore which would indicate a CG200.

so ball park 200cc.

you wont find many upright vertical engines in smaller displacement.

below 190cc you end up with horizontal Chinese Honda clones. common in pitbikes and C90 clones.

Ok thank you very much!

Incorrect XLsior. The FMJ indicates that it is 150cc displacement (assuming it's correct). It's probably a 62mm x 49,5mm bore x stroke engine, so basically a CG125 with a bbk to turn it into a 150. Zongshen never made a 62mm bore 200cc engine that I'm aware of.

They did a 63,5, which was the 163FML , and the 167FML which was based on the Yamaha TW200 engine (roughly speaking).

Also, there were/are plenty of sub-200cc CG/CB clones that have been sold, just not in the US and presumably AUS. They are still cloning and selling the CG125 throughout the 3rd world, and there are also some sold in Europe as A1 compatible. For that reason, it's actually somewhat hard to get the CG200/250 in Europe, because they don't want people making their A1 legal bike too fast.

I would venture a guess that if you excluded utility trike sales, as they're super popular, if you added up all of the Chinese CG sales globally, I wouldn't be shocked if the CG125/150 outsold the CG200/250 by at least 10:1.

The same can be said for the horizontal motors, anything bigger than a 125 (but usually a 110), is usually a toy for decadent westerners. I think the CG125 is generally preferred over the horizontal 125 for several reasons: durability/longevity, 5-speed vs 4-speed transmission, and conventional motorcycle frame vs underbone frame.

@op ... Measure the height of the cylinder from the crankcase to the start of the cylinder head. That will give us a better idea.

Thank you I've! I've been trying to research and this is the conclusion that I came to as well. It seems it is a 150cc engine after all. It makes roughly 11hp.
