Question about Yamaha XJ 650 Motorcycles
You could have a couple of things wrong. It could have a vacuum leak. The best way to find a vacuum leak is to get it started and use your starting fluid and spray around the carb. If the engine revs up, then you will be able to find the vacuum leak by where you spray. Another thing could be the idle screw was adjusted out and not idling high enough. Or could be that when they rebuilt the carb, got some of the debris out of the float bowl in one of the jets. I would start by checking for vacuum leaks and set the idle up a little bit. The idle screw is on the side towards the top of the carb. It will have a spring on the screw. It doesn't take much to change the idle.
