Don't mean to sound like a smartass but how old is the battery?

[jimbowv]

less then a year

but even once i jump it ...it will not run when i take the jumper cables off

[beherenow71]

Still could be the battery, had that same thing happen to me on a car, it was the battery then.

Bad battery.

[jimbowv]

But would it still run when I remove the jumper cable

[beherenow71]

If the battery is bad enough, it would die once the cables are removed like you said happened.

Do you have a digital multimeter? What does it read with the bike off. What does it read with the bike on @ 4000 RPM?

find the wires coming up from the alternator, and take the connector apart, inspect, clean, and firmly reseat. then go thru each fuse, checkingyour wiring diagram for a main fuse or breaker away from the fuse block. a weak or bad battery prolly plays a large part in the problem. check it bike off, trying to start, and running voltages
