The main thing about carbs is that they don't like to sit; they gum up easily. If you use them regularly, they work just fine. My M900 was a daily driver, so I rarely had problems with it. The original carbs wore out and had to be replaced at 185K. I got a set of used carbs with about 30K on them, and used them for 80K, so those had about 110K on them when the bike was mashed, and they were still working fine. Once you get the hang of using the choke, they were fine for starting and all. I had to upgrade my starter circuits for the colder seasons; stock it didn't like to start below 40F (5C). But once I went to 4g cables, and added a dedicated ground cable, then as long as the battery had a decent charge it started fine down to 20F (-7C).

My M900 cad a carb, and I had a good mechanic (aside from his bouts of shooting seagulls with his BB gun and insisting about telling me about it), that was happy to tweak it. But I am new to FI and last night I had my first issue with what I think was that... It was cooler out last night, and before it had a chance to warm up, the bike didn't want to start and kept dying. I eventually got it started without wearing out the battery, and kept the RPMs up high enough to not let it die. I think no more quick trips to the post office 'till I get to know the bike a little better.

"Didn't want to start and kept dying"?

Turning over slowly, or firing up fine, then quitting? How long was the duration of run time?

Right NOT turning over slowly - but not exactly starting up fine, either, which made me think it was the fuel injection (?) rather than the battery. It turned over several times before starting, then quickly cut out. This was after going only about three blocks/minutes then turning it off to mail my package at there PO. Then this morning, it started and ran fine. So, I'm thinking it had to do with the cold and the fuel injection, but I'm not that familiar with this machine.

Yeah you know I'm not that experienced with mine either.

Haven't had it cut out, (I imagine plugs are original?) but it'll be quite plodding on startup sometimes. I have no idea of the age of the battery, so I have that in mind.
Somewhere on here, someone was selling one, and his started up on the button press, it was crazy. He attributed that to a brand new battery.

I have an FI model and use starter fluid and hold open the throttle for a second to get her running on cold mornings that she won't start. Not an issue after that.

I'll never go back to carbs. FI for life now that I know how maintenance free it is.

Wait... That's unusual to start right up with the button press? B'cause that's what mine normally does...

You know... I was warned about FI before I bought my '98 M900 that had a carb. But I think I now see the light.

I have a pic I took at Ducati Seattle - I know it's not a full shot, but I was trying to be discreet.

Also, not entirely sure the best way to post this since you can't pull links from Flickr, but I'll try...
