So I got a bike not to long ago to work on and it wouldn't start when I got there. The owner says it hasn't been started in a year and a half. Got a good deal on it and took it home and got it running with state fluid. But it wouldn't stay running. I took it apart and cleaned the carbs, new spark plugs, new air filter, and oil change i it and now it starts every time and idles decent but when u go to give it gas it wantsto die. It will rev to like 3k ram and then die. But when I fully come it, it revs higher than that but given gas it will die. Can someone help me determine what the issue is please??
