I may find that to get the performance I want I may well be smarter to sell this bike and get something else that's more accepting of upgrades. I like the bike but the top speed of 32 mph and taking a city block to reach that speed is unacceptable.( For performance, you have one of the best 49cc platforms. Access to parts just depends what frame and fairings the engine was stuck int, but it's a good little motor. I've never worked on that model, so not sure what to tell you there. Sometimes you can get to the bowl to change a main jet without removing panels from the underside. It's not fun, but it may work if the carb is that bad to get to otherwise. What you're seeing under the seat where you say the gas and oil tanks are, are probably just filler necks and caps I'm guessing. If that's the case you may be able to disconnect/remove the battery, remove the bolts holding the seat bucket in, and then take the caps off long enough to slide the seat bucket up and out. I'm 300lb and none of mine did only 32MPH stock. Yours is likely either out of tune (carb or CVT) or restricted. |

Prob 10.13:1 final drive ratio. 10.13:1 and 13.55:1 are the most common Chinese long case ratios.
The short and long case CVT covers are a little different. Different depths.
The FM/QMA should be ready to accept 90cc parts. The problem with them is that you can't really find 90cc cylinder kits for a 10mm wrist pin and unless you can get the cylinders just for them, you can't really get a 50-70cc that works without modifications. They're a great engine if you want to to a full build and replace the crank with a 42-25mm stroker with a matching cylinder kit 50-54mm bore. It's basically 90cc cases, with an oddball crank and cylinder kit.
