Went to start my '03 XB9S last night. Would not idle unless I held throttle open to tach about 2k. Also loud , high pitch sound from what sounded like under air box. Riding at speed on the way home no problem. When I got home idled with no problem . No noise from air box. Shut off and restarted and idled no problem.
If this is fuel pump going south , how much trouble is it to replace?

Could be. Sounds like what happened to mine. Mine died as I turned in to my neighborhood, then fired up but wouldn't idle, I had to give it gas. Then in the driveway it'd idle. I replaced the pump and while doing so noticed the ground wire on the pump was loose. I think this was my real issue, but I went and replaced the pump and filter while it was all apart, was only a little over $100.

FWIW the old pump was crazy loud, like a whining noise. The new pump(ford mustang pump) is pretty quiet. Almost have to listen for it when you turn the key to hear it priming.

If you're handy not too bad. A few parts are a royal PITA though. Here's a thread I made when mine went out:

Got it done, thanks for the info . Saved a lot of time. Didn't have to pull swing arm, old one out- new one in and back on the road.

and FWIW I've probably put 1000-2000 miles on my bike since I did the pump and it still runs great. Starts and idles better than it used too. I believe my issue was really the loose ground. Was your ground tight?

A little loose. Don't know if lose enough to cause issue or not. But did put lock washer on it. Took about 2 hrs start to finish. Had to work screen a little to get back in , having the write up really saved the time there. Did not have to figure it out on my own.
