Hello all,

I am seeking help for my end of the world problems with a 04 650. She has been sitting for an extended period. After changing the batter and starting her up, everything seemed to go as planned. Then a mile into a get to know me again ride, severe loss of power with eventual shutdown. She still idles but will not move under her own power. Any throttle twisting kills the engine. It has about 6300 miles on it. It does sit unfortunately. Looking for the things to check in the most logical sequence.

Thanks

My 04 started acting up never actually stopped running and when I replaced the spark plugs started running great. One mechanic thought fuel pump might be the culprit and plugs were further down the list. I decided that plugs were the easiest and less expensive first step and that seemed to take care of it.

How long had she been sitting? Did you put fresh fuel in? What does she do running on the centerstand?

Sound like your injectors are fouled or gummed up from stale gas.
Try adding a can of Seafoam ( or similar fuel injector cleaner) to your gas to see if it cures the problem.
You may have to let it idle a while for the injector cleaner to have some effect.

Unfortunately, she sat for over a year while I was out of the area, fresh gas was used. Seems to be no difference between center stand orme sitting on bike have not ran it on side stand (is that even possible?). Seemed odd to me it ran for the mile or so and then died. I suppose the small bit of gas left may have had trash in it and it just moved on down the line. Surprised that it does not have another fuel filter other than the tank screen.

Unfortunately our new gas blends just doesn't have the shelf life of back in the good-old-days. When left setting for very long without additives like Sta-Bil or Seafoam the gas will separate and leave varnish deposits. When fresh gas is added those deposits will turn into a gummy substance. Running the engine will then pull that gunk into places that will get plugged up with those varnish deposits. The mechanics at boat marinas experience that a lot. If you go to the closest boat marina that has a good reputation for knowledgeable mechanics. Ask them what they recommend. Of all the mechanic fields, I believe the marina mechanics have a higher rate of experiencing that problem you're experiencing.

Good Luck

Happy Scøøterïng!

+1 Animal's suggestion.
Marina mechanics (and stores) and I have become great lovers lately. I had a similar issue with my truck that sat for over a year. Idled okay (a bit rough), and even ran (a bit rough) for a couple of miles... until it warmed up. Then I couldn't even get it to start, much less run worth a crap. After a cooling off period, I could get it to idle, and even idle smoothly, but once you gassed it in gear, it shut off. New plugs, new wires, cleaned intake and and and ...

Finally, because I did this for a while (trying to troubleshoot), I had to put replace the fuel pump. They replaced the gas, but she still ran a bit weakly, and the mech said "don't invest much in her, she's on her last legs". Took it down the mariner and a mech down there heard it while we talked about a boat, told me to buy some sea foam and put that in, and now, she runs pretty darn good!!!

Go figure!
