Qingqi Recent Questions, Troubleshooting Help & Support

Hello, Qingqi. I found this article that says SJ10W-40 is best for a 49cc gas-powered scooter. http://www.ask.com/vehicles/type-oil-use-49cc-gas-powered-scooter-e2ec930521cd0a6a

I am having the same problem and I am having a hell of a carry on trying to get the v5 for my sinnis eagle as it's down on the dvla as a Qingqi varient so I am really confused I know after doing some research Qingqi go by the name of sinnis in the UK but it's really confused me and I have been trying to get the v5 for 4 months now!!!!!

What is the specific problem?

There should be a VIN plate on the steering head containing all the information. Typically on the right side (if you're sitting on the bike). Turn the bars all the way to the left and look on the frame just ahead of the gas tank.

Contact the dealer that makes sells the bike and ask them. This bike is chinese and there is no info on them or anyone willing to help.

Sounds like you have a blocked pilot jet so you will need to remove the carb and clean the jet.

You say that it did 70 after the belt was changed, this seems to indicate that the belt could be slipping. Either replace the belt again or get hold of some belt dressing which makes the belt grip better in the pulleys. Another thing to look for is a blocked exhaust port and muffler box plus look at your air filter to see if it is not perhaps restricting inlet air flow.
