It has fuel going into the carb. it has a good spark. battery is all good as had it tested by a mechanic. i have recently upgraded to a 70cc kit but since the otherday by putting transmission oil into the transmission it ran for about 6-7 miles but later that day it didnt want to start. i have emptied the transmission out but still no luck. help!!
It's a strange coincidence that your scoot started acting up after the transmission fluid change. The transmission on a cvt scooter is separate from the engine internals. I would suspect your 70cc kit is starting to make things act up. I would first check the plug to see if it has been running lean. A really white plug might indicate that you need a richer jet or have a vacuum leak. Second, torque the head studs to the proper spec. The can loosen after run in and need to be retorqued. Lastly, start it up with the rear wheel off the ground. To do this safely put it on the center stand and put the front tire up against a sturdy wall. Give it a good rev. Does it take longer than normal to drop back to idle? If it does, you may be running lean. A quick way to check for vacuum leaks is to spray some carb cleaner around the base of the cylinder and the head and see if your idle increases. Kits are not always the quality of an oem cylinder and the thin metal base gaskets that come with some kits are prone to air leaks. At worst case you could swap on the stock cylinder with some fresh gaskets and see if it does the same thing.

Sounds like it may be drawing air around the intake somewhere. Let it idle and spray around carefully with wd-40 until it speeds up. This will reveal the leak.

You have two pumps,I guess you know that ,if you already did one. Did you check fuel pressure at the rail and check out the electronic pressure regulator? What codes are coming up and do they stay set?
