Only one cylinder is firing 2000 yamha v star 650

SOURCE: NEED TO REPLACE REAR TIRE YAMHA VSTAR 650 2000

A service manual is a valuable tool with an aging bike. I suggest the dealer/mfr. or Clymer books. In the meantime, go to the library reference section...646 stacks should have what you need.

SOURCE: how do you remove a yamha dragstar 650 petrol tank

1. unscrew the 3 allen bolt around speedo.
2. lift speedo section up & undo speedo & wire plugs
3. 1 bolt each side at rear of tank. Undo these
4. lift rear of tank then slide towards rear of bike on angle.
5. once feel it slide up then lift the front upwards & forward.

So check the compression. The valves could be set wrong or are not sealing well. You didn't mention any smoking so the piston rings should be okay. The most likely cause of the problem is a pin hole in the carb diaphragm or a carb needing to be cleaned. Go ahead and drain the float bowl then remove it. Now clean the carb with spray carb cleaner. With a bit of luck the cleaning alone will fix the problem. Please rate my answer. Thanks.
