so the deal went sour.
now im still stuck with an 05 speed3. still needing some cash, and now to add to that, completely in love with the ergos and sound of the 900SS.

any suggestions besides the obvious? anyone know anyone?

Not sure why it went sour...? Don't be put off by hard starting from the flatslides ... they are AWESOME carbs (and worth prolly around $700 even used), but they take some getting used to on cold starts... your seller prolly never learned the drill, and you've prolly tried it once. Don't give up. A couple 1/4 or 1/2 twists will do, maybe open the throttle slightly if it's really cold. It's a "touch" thing (I quote Chris Kelley (www.ca-cycleworks.com) here, whom you should get to know if you do get a Duck), you'll get used to it. By the way, Chris's site has a LOT of info about the flatslides (better known as FCRs) and 2-valve Ducks in general.

Of course, if there were other issues, um, NEVER MIND!

Apropos of which, is was about 50 degrees F this morning in Boston. Coldest start since I got the FCRs. Yeah, they were a little balky. You just have to goose the throttle a few more times, and maybe wait a minute to see if they're gonna need a restart.

Still love the FCRs. Best mod I've done, and I've done a few.

it was 36 degrees in the morning and two twists, two tries and the bike is running. I had much more difficulty with them before I had them rejetted by BCM. otherwise they are much better instruments than the original carbs.

On the flip side, the stock carbs are worse in the cold weather. They start better yes, but then they ice up and won't run well at all. Ducati even offers a cold weather carb kit with oil heated float bowls.

FCR's are they way to go with an air cooled two valve.

Hmmmm my 800 SS started and ran just fine at 32*a few mornings last week..... ain't fuel injection great

and as goofy as I thought fuel injection with a choke was at first, now I think it's the best thing since sliced bread...LOL

"simpliity carried to its ultimate extreme"
Fabio Taglioni said that. I don't think he had fuel injection in mind. Progress I guess.

I don't know, IMHO fuel injection is far less complex than carbs. Far less mechanical parts to need adjustment.... no floats, no jets, ect... just injectors, a couple sensors, and an ecm. Of course though the tinkerability for the shade tree mechanic isn't there on a fuel injection..... But I spent plenty of hrs trying to keep the carbs synced on an H2 years ago so that part of tinkering I no longer miss

yeah, now i just hook it up to my laptop.....

I put 39s on my 900sp 3 seasons ago and never looked back. Cold starting takes getting used to but once you get the routine down it's no sweat. When it gets into the low 30s I turn up the idle 1-1/2 twists, give the throttle 3 full twists and let her rip. Might take two tries, rarely three but once it starts I don't touch the throttle for a minute or two then she's ready to go.

The difference in throttle response over the Mikunis is night & day. Feels like you have an extra 10 ponies.

Wanna pass a line of cagers on that straight just grab a handful of throttle and hold on.

And no icing - period! That was my main reason for going to the FCRs and they cure that problem 100%. If I keep the revs between 4 & 6k I can get 175 miles on a tank no problem, hi 40s mpg. On the boil it goes down to low 40s, high 30s. If you like the pre-99 carbed SS, FCRs are the way to go.

F/I is probably better but if something goes haywire in the middle of nowhere in the middle of the night at least you have a chance with carbies. That said my next bike will likely be an ST.

FI may have less mechanical parts, allow for better performance, be more reliable, be more tunable and work better in variable temperature and atmospheric pressure environments but it is not simpler. Just having to have the fuel rail and delivery system under pressure takes care of that let alone ECMs and injectors. To be sure, the FCRs are in fact fairly complex pieces onto themselves with variable slow/main air & fuel jets & screws, needles of varying widths and tapers, roller bearing slide. In effect, trying hard to stave off the inevitable victory FI would have over this carbed application. In concept and in it's more original application (say with the bevel drive Ducatis of the '60s and '70s), carbies are a lot simpler.
