Have you checked the compression? Could need a rebuild soon! Or, it is flooding overnight? Do the 650's have a fuel shutoff?

its a 600 but yes it does have a shut off. but i ride daily should i still shut it off. i always assumed shut it off if you were not going to use it for more than couple days. but not sure i could be wrong let me know. maybe i should replace my choke plungers would that help or no. would running it out of gas harm something or no thank you

Running it out of gas would not hurt anything as far as I know. I would shut it off overnight and see what happens - I know that the when you leave some 400 and 500's fuel on overnight they will not start due to extreme flooding.

One thing to check, pull the carbs apart and check the needle/seat. If they are bad, you will flood the engine just sitting. Turn off the fuel if you leave it sit overnight or trailer and see if that helps. On mine, the needles have a groove in them, but are still sealing. They are about $15-18 each to replace.

i turned the gas valve off last night and went out today and one pull it starts right up so would this mean any of you could narrow a problem down to something specific in the carbs dont want to just throw parts and a bunch of money at it or should i just gut the carbs and rebuild with new parts thanks [thumb]

Pull the carbs apart and inspect the needle/seat assembly. If there's a groove in the needle, it's time to replace as it's probably not sealing anymore.
