'01 748S running rough, won't start

[edognight]

My bike is usually a runner, I've never had a problem, but the other day it would barely start, and when it did it ran really rough and sputtered horribly.

If i was a betting man I'd say it was the plugs and wires, but I am not really a mech. I had the exact same thing happen on my '91 harley.

It came on suddenly with no previous signs...any guesses?

01 748S. about 15,000 miles. no previous problems. belts and valves just fine and no flaking.

thanks for lookin!

Fuel pump sounds normal? If if were me I would quickly check spark on the plugs and move on. I've never had plug or wire problems on my 996, but have had a fair number of fueling problems. 1st problem - bad TPS. 2nd problem - split fuel line inside the tank. Even something as simple as bad gas/water in gas would cause this.

I´d guess ECU connection or battery. Check the wiring for loose plugs.

Does it rev? Does it sputter at all revs?
