I did the CDI wire cutting modification a couple of weeks ago and initially my scooter worked fine but now I have noticed that I have to let the scooter warm up quite a while before I can use it without the engine cutting out. Also I don't seem to have as much power going up hills as I used to. I'm not sure if this is related to the CDI modification or if it might be something else. Anyone have any suggestions? I'm thinking either spark plug or Carburetor. Thanks!
