1150 Stumbling like a low on gas Airhead?

[r65_steve]

I know many of you are at the Rally. Took the bike out to warm up the oil for a change. The fuel light was on so I know it was low, with 150 miles on the tank (Rockster doesn't get a long range(. After some side to side sloshing, the light went out and as I proceeded to the gas station, it stumbled like an old airhead when it's low on fuel. I filled it up and for the first mile or two same issue. I stopped to spectate a traffic accident and the last 2 miles to home seemed to be OK. Any guesses as to what might be up? Might do some test riding this afternoon when the oil change is done. I have a big trip planned in a couple weeks and now I'm a little worried.

Bike has 40,000 miles. 2004.

Doesn't sound like a trip breaker, change the spark plugs.

Water in fuel that was in the bottom got agitated when you sloshed it side-to-side. Then settled back to the bottom later. I would add a half bottle of IsoHeet in the red bottle.

Took it for a test ride and it got worse. Way worse. I rented the trailer and hauled it to a shop. Tech seems to think its a bad coil. He swapped one in while I was there and it was instantly better. It's still at the shop to get a full diagnosis. I'll report back.

Yeah, that's what it was. Replaced them both for good measure. Back in business!
