JCL-MP 250 A OHC or OHV motor By 4950cycle (Read 2,053 times)

[4950cycle]

Hi , I'm new to this forum. I just bought a 250 water cooled scooter at Killermotorsports.com. Would anyone happen to know if this scooter (JCL-MP 250 A) with a Linhai liquid cooled 250cc motor is a Over head cam, or Over head valve ? And also, Would this be a GY6 style motor or are all GY6 style motors forced air cooled ? Thanks for your input. John

Look at the engine itself. If it is a horizontal engine it is a Linhaie and if it is a vertical engine it is a Honda clone. I have a Honda clone with GY6 indications on it. Linhaie is 257 cc and Honda is 244 cc. Check the Vehical Emissions Control tag. Mine say Jonway Motorcycle USA and has the 244 cc on it. It has a MFG tag that says Shanghai JMStar Motocycle.

A quick look at the engines or the rated cc will help you determine the engine style.

This scoot uses the Linhai engine. All 4 stroke Chinese scoots are OHC.

Oh yes, I forgot to say my Honda clone is water cooled same as the Linhai engine is water cooled.

Cruiser is correct, but have you checked the engine style and Vehical Emissions Control tags for personal satisfaction? Done your homework and know what you have for sure knowledge.

Enjoy your ride. It is ridding time most every where now. At least on some days.

All GY6 engines are 50 to 200cc and are air cooled. None of the 250s are GY6 so don't use that as a reference. The Linhai engine clone is based on a Yamaha design and the Yamaha Majesty Manual is the reference to use for engine service. However, the scooter itself is a Honda Reflex clone and you can access that manual right here. Confusing eh?? That manual will apply to some degree but the clones are much different than the original. Rich

Thanks for that clarification Bashan, Rich. I often wondered about that GY6 on my engine. I have a 244cc engine and as you say the GY6 was only for the lower powered engines as I was looking around for information.

It is then a Honda and CFMoto engine, not truly a Honda. I have found a Linhaie Yamaha business agreement but so far not one from Honda and CFMoto, But I have read articles of such an agreement. Any knowledge of such a business agreement?

My engine is somehow connected to Honda or there would not be Honda names, GY6, on it and the Honda dealer in town said their parts would interchange but they would not touch it for service or repairs. Strange attitude as money is money.

Bob, you don't want to go out and buy Honda parts. Not that they won't fit in most cases, but the cost is up to 10 times what you will pay if you order over the internet.

You've got a GY6 designation on your 250? I have no explanation. Is it in the serial number or what? It's definitely not a GY6 though. Yes, CF Moto and Honda struck an agreement years ago and CF took over the manufacturing of that engine. If I remember right CF even made some of the engines Honda used for various applications. Cookees knows a lot more about this whole deal than I do. I'll send him a PM and see if he can add anything. Rich

So true I don't mind them making a profit, but I bet the parts are made in china just like most everything else is.

Yup. I have a GY6 on my engine. Could not remember where I saw that but went out for a look. Found it on my oil drain plug. No special designations or on paper work, but there it is for sure.

[Alleyoop]

The Oil Drain Plugs are pretty much standard and Just about all of them have GY6 imprinted on the plugs. YOU DO NOT HAVE A GY6 motor. You should have a PLATE on the scoot and that should give you a lot of info. What does your motor look like is it Horizational or Vertical(talking about the head). Is the Valve cover pointed to the front or up towards the sky.

I posted all that information near the top of this thread. I know what I have and was attempting to answer the original posters questions about engine style. The GY6 was just something I remembered finding on my machine. I know that I have a Honda clone by CFMoto water cooled engine.

Never heard it the original poster has found the answer he asked for.

From what I was told, CFMOTO started producing Honda's water-cooled engines in 1999.
