I own a 2003 800 Dark and recently installed the Two Brothers slip on exhaust. After the install my bike has started to jerk and spit at about 3-4,000 RPM's. After checking the Two Brothers website I found that they haven't done any research on the 2003 bikes. As a result I have to figure things out on my own. Based on my findings, does it seem applicable to fiddle with my fuel maps (via a power commander), and/or install a more air-friendly filter?

Sounds like it's running a bit lean. Using an open air cleaner will only make it worse. You'll have to richen the mixture.

Yes I would definately recommend a power commander or the
FIM replacement ECU and both on a dyno if possible.....the difference is worth every penny. I know people will with good intentions recommend a techlusion......but they appear to be woefully short of the desired adjustablity to properly tune a bike.
I am not sure if you meant to say open the airbox or just replace the stock filter. (the stock filter is actually good.) If opening definately try the power commander.
If you can get it on a dyno so much the better.

the stock air filter may not stand the abuse from water if you ride in the rain, with an open airbox. i think that is the only advantage the k&n type would have.

Retro..
What is the FIM replacement ECU, where can I get it from and how much would it cost? I've seen monsters with two pod shaped air filters replacing the stock airbox. Would that be a good option? I priced a power commander at roughly $330. With the power commander, I know some type of mapping is needed. Where can I get that from? If I bring my bike to a dyno tuning business, can they perform all necessary modifications (i.e. balancing air, fuel ratios)?

The FIM replacement ECU replaces the stock 5.9ECU and the whole immobilizer system......

Here is some info...

http://www.manleycycle.com/

The price for the FIM is $650.00.....but it is fully mapable...

it appears there are several power commander certified shops in Ill. and in Wisc. don't know who is closer to you....and they definately should be able to adjust your bike to run properly.....I do not know if there is an FIM Ultimap certified shop in your area so the power commander is prolly the best route....I also believe people here do their own tweaking with a power commander without a dyno and seem to be happy and even those with the techlusion seem to be happy with the results they are getting.
If you have any questions about which way to go I can recommend calling either Doug Lofgren or Manley cycle, ......they can answer your tech questions much better than I can......I believe quite a few people here have pods and seem to like them.....my understanding is the duc air box is designed the way it is for a reason and that it acts as a resonator and it seems to even resonate better open....there is some explanation of this in one of Lofgrens reports......but again Manley, or Doug can answer these questions from firsthand experience......BCM is also a good source; see link on FIM site.
I live in Minneapolis where Doug and Manley are so if I can be of any further assistance somehow let me know......they are good guys, very helpful.....and have done it all.....

most cost-effective solution would be to have your dealer tune the stock ECU for a richer mixture by fiddling with the allowable CO levels and the TPS. this can be done with the ducati diagnostic computer, but if your dealer's not too savvy, i wouldn't recommend it.

next cheapest route would be to get a TFI box from www.techlusion.com. you can dial in your settings pretty easily with manual knobs. cheaper than a powercommander but not quite as versitile.

powercommander's next in my oppinion. find them pretty cheap at www.kyleusa.com and there's a reasonable number of maps to play with for free from powercommander.com. if you really wanna get it RIGHT though, you'll have to factor in a couple $$ for dyno-tuning.

the ultimap 5.9 replacement (FIM), is the "best" route but it's definately the most expensive.

Installed the Stainless Steel Sil Moto high mounts and my bike had no power below 5000 rpm and was very week above that. Bought a power commander III and downloaded 5 different maps off the site. My friend and I used his lap top to load the different maps to find the best one - using the seat-of-pants-dyno. Took about 2 mins to find one that was really close: the bike runs better now than stock, defenitely more power. I would strongly suggest the power commander!!

The local ducati shop are a bunch of bafoons. There are two Harley shops that are certified PC3 tuning sites with dynos. Next time I'm over there I think I'll let them tune my duc ::)
