The above says it all.

There are differences in the clones and yamaha jog minas. Nothing big, except a clone axle will not fit a stock jog wheel.

1E40QMB 1PE40QMB 1E50QMF NF1E50QMF are a few versions of some clones.
Heres an explanation copy and pasted from scrappydog
Chinese bikes and ATV's can really be confusing, that is why scrappy dogs was started. There are two identifications to remember by using this site for help, not only to know what you have, but to get what you need. The first is the engine type. While this site uses a simplified directory at the left, you really need to know the engine number to get your parts right. This engine number is typically in two parts on the same stamp location. Most of the time the numbers are stamped on the left side of the engine, under the belt cover, near the front close to the engine mount to the frame. The bottom number is the reg. number, the top number is the one to pay attention to, this is the engine identification number. It tells you what you have. Below is a picture of a number plate for a 50cc 4stroke, also known as a 139QMB.

The engine number is very significant, and reveals alot. Take for example a popular engine, like the Honda Monkey (chinese copy) The number stamped on it is a 1P39FMB. The first number is the number of cylinders, the second, a P, is code for a horizontal engine. The next 2 numbers, 39, is the bore diameter in mm, 39mm bore. The next letter, F, indicates that it is natural (not forced) air-cooled style. The next letter designates that it is a motorcycle engine "M". The next letter reveals the full engine displacement. B is code for a 50. C for a 60, D for a 70, F for a 90, G for a 100, H for a 110, I for a 125, J for a 150, and so forth. Notice that the size graduation increase is indicated by an increment in the alphabetical letter? It's no coincidence. It's amazing to me the cooperation in standards of China. There is also prefix letters on many, designating the manufacturer, like Quinjiang (we have them all on file), which stamps there acronym, QJ, as the first two letters in there code. It's also very revealing, as the QJ139qmb is quite different then the other 139qmb's. It uses the 1E40qmb (2T) transmission components, and the engine case is a little different. There are also suffix numbers at the end, which designate iteration levels, like -3 in the photo below, which denotes that it is the third design, or improvment. Call or email us if you have any questions. We love to help. Here is the Chinese engine code chart with the example of the JOG 2stroke engine number 1PE40QMB-4




Some engines have the number plate on the upper rear side of the belt cover. GY6 engines are on the fron, bottom, left had side near the centerstand pivot. 2stroke JOG's are near the rear wheel like Honda Spree elite and DIO. They are often on a sticker on the belt case. Sometime the airbox needs to be removed and alot of grime washed off on the 2strokes. By federal law they are stamped on the engine case and are there, even if you don't see it at first inspection. Either way it will help you significantly to know this. As far as the chassis body parts go, you can reference your body appearance to the listing shown in the Chassis directory given at the left, or simply click here- www.scrappydogscooters.com/CHASSIS_PARTS.html
This list is growing weekly, so if you don't see your bike here, check later, or better yet use the Parts Finder form on the home page. Scrappy dogs are committed to making the Chinese vehicle market easy and fun for everyone, and affordable too!
Thanks for the question, hope your not so lost anymore.
MO!

Thanks so much Birdman.I really appreciate the effort.Suffice it to say the economy has caused my retirement to be a lot rockier than I had planned so gotta guard mt pennies.I live in an industrial ,very pro union community, where used Chinese bikes are anathema so they can be picked up very cheaply.

I hope yall don't mind me asking
But first. I'm looking to.identify the upgear kit i need. I have a 2010 jonway 50cc 2 stroke. Upgraded with 70cc naraku 2 ring piston. 22mm nibbi carb, polished intake with carbon reeds and a flypig expansion pipe, which I guess I got lucky with because the bike is truly FAST for the street.. it has a malossi variator and 5.or 5.5 roller weights.. so fast to me is super pull from mid band to top speed which only went from 40 -45... but now it will push you back some taking off.. the problem is definitely gearing.. I have not.pulled the secondary yet.. the bike pulls so hard but is winding so high its just got a lot more... is there ANYONE who would know what gears I have stock? I can calculate what to order but was hoping to order before hand ... I am confident 11 or 12 horsepower is on tap now.. and I want 60 mph out of this bike max and 45 to be a cruise.. I'm thinking maybe I have 13/52 and need 13/44 or slightly less on the big gear to get 25% spread on the power band... I have 170/12 tires and thought maybe a taller tire would work but I don't know about rear wheels and changing wheel diameters.. any help or correction, clues or breadcrumbs is truly appreciated 🙏

I assume you have a long case Chinarelli, they usually have a final drive of 13.5 to 1. Ideal ratio is around 10 to 1. Some of the Vento and CPI scoots had them..
