It may not be restricted. Could just be out of tune...

Try lighter cvt roller wieghts. There may be intake limiters, exhaust limiters and or a cvt limiter, as well as an ignition rev limiter. The other guys here know far more about this than I do, but There is a starting point.

I also have a Thunder and after a lil research I've seen where people are saying that the 1P39QMB are actually 64cc compared to the 139QMB are 49cc is there any truth to this!

Not if youre not hitting 45. The fact you say its slow probably means not

A lot of people say the 'P' means it has 69mm length valves instead of the normal 64mm length valves.
Upgrayedd has a new Taotao and his engine has the 'P'. It has the 69mm valves.

is there anyway to find out other than actually measuring the piston

is there anyway to find out other than actually measuring the piston No! First, unseal the carb. 90GTVert has a thread on the Project Taotao. He has PDI (Post Delivery Inspection) videos that you should watch. Then you can tune the carb. You probably will have to put a bigger jet in the carb. They are set to run lean. 49ccscoot.proboards.com/thread/6365/project-taotao-stroke-experiences-upgradesSecond, tune the CVT. Others know more about tuning a CVT than I do. |

I had a TaoTao ATMa that was a " secret 63 " and it ran like a dawg . I blew it up and put on a Air Sal 50mm BBK 82cc wow the extra power was so much noticed on take off and uphill but it had the same top end 55 on the speedo but GPS said 44 MPH . Note I also replaced the 8g rollers with 5g and wow it made a huge diff too .
A buddy had a TaoTao Thunder which is much better designed as it rode and handled better and had way better headlights . My ATM was like having a candle in a cave . His would only hit 30 and 35 after break in but we never touched it other than oil change . I think his may have had the variator restricter washer .
Yes some have diff valve sizes . The p means horizontal . This is copied from Scrappydogscooters " 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 "

The CVT cover? Tap it with a rubber mallet. Sometimes they seal against the gasket and tapping will break it loose.

It may not be restricted. Could just be out of tune... Ok Brent...hold up.. Where did you get the digital speedo for this Taotao? I have somebody asking me to find one. Also his analog speedo only goes to 35mph on his TaoTao Thunder and the ATM and Speedy model ones I see go up to 50 mph. Reason he wants either the analog 50mph one or digital one is because with his 80BBK..CVT and carb tuning...it buries the 35mph stock speedo it came with. Therefore he has no real idea how fast he is going after he hits 35. The speedo just 'pegs' and ya gotta guess...  So where can I get him the 50mph or digital one? Thanks, Glenn |
