my 06' monster from 0-2100 rpm's is very unresponsive and often dies. it is rideable, once it passes 2100 rpm's the throttle is very responsive and seem to ride just fine. i thought i might be bad gas so i put some new gas w/ fuel injector cleaner in it and tried riding it out (1 hour) but didn't seem to work. to get the bike to get over 2100 rpm's i need to open and close the throttle rapidly and then it's fine once it gets to 2100 and upwards. could someone point me in the right direction to troubleshoot this by myself or is this a bigger issues that needs a ducati man to service it? could it need to be remapped? a bad sensor somewhere? any thought or advise would be nice. thanks
Umm....
That actually sounds pretty normal.
My '06 Sport 1000 gets unhappy riding around under about 3500-4000 rpm in anything higher than 2nd gear.
That's just the way they're tuned.
Troubleshooting question: did it just start happening or been doing it for awhile?

normal??!!? far from it. this is really all starting/idle/1st gear issues, anything passed 1st and it's fine until i come to a stop light/sign. maybe i should of went into greater detail: when i get ready to take off i need to crank the throttle back and forth (one should only have to go back and not forth multiple times) until it finally jumps passed 2100 rpms, under 2100 it's jumpy/dies/and throttle has very little and delayed response (not normal). over 2100 the throttle is normal, i twist and the engine reves i untiwist the throttle the engine slows down (like normal). while riding, anytime i come to a stop the engine dies and i need to start it back up, crank the throttle back and forth quickly multiple times until it responds when it gets over 2100 rpms, then release clutch and ride..........very next stop same thing basically dies even before i come to a stop and then i need to repeat that same process again of the cranking the throttle back and forth until it responds like a normal throttle over 2100.

it just started (probably for a good reason though), the last time i rode my bike was 7 months ago, everything ran smooth then. BUT.....since then i've taking off the generator cover, clutch cover (wet clutch), exhaust and put them back to what i believe to be correctly. no stabil was put in the gas tank thoughout the cold WI winter.
Sorry about that. I read your initial post and thought "Rolling on the throttle, it's sluggish from wherever he's riding it to 2100 rpm? Why is he lugging the engine?"
To me, it still sounds like bad gas. I had the same problem with my '03 620 after winter storage (Maine) without Sta-Bil. It started toward the end of the tank of gas it was stored with, and took me about 2 tanks worth to clear out.

my explanations are never great (could be because i'm a noobie on a bike with no auto experience whatsoever) that was gonna be another question "how long can it take IF it is bad gas?", because it seemed to be getting a little better since i first tried but kinda seemed like progress is at a standstill. is bad at low rpm's and normal at medium to high rpm's constistant with bad gas? is that how your was? i probaby ran 1 tank. is it best to sit there and roll the throttle at the low not so good rpm's or to ride it at medium rpm's to try to work the new gas in?
Mine felt like it was only running on 1 cylinder when it was at idle - low rpms. Don't remember specifically where in the rev range, but it felt more like itself as I wrung its neck trying to get power. I definitely remember having issues getting moving, but staying moving wasn't a problem. It was a bit anemic, sure, but it'd move.
I would think that the more gas you could move through those clogged injectors (if that's what it is) the sooner they'll be cleared out. I'm sure someone else with more experience will chime in.
Also wouldn't be a bad idea to check your plugs. You know, just cause.

thanks, right now this is all i have so i guess i try to ride it out some more. i changed the plugs already which didn't seem to do anything. thanks again.
I HAD stabil in my tank over the winter (CT) and when I took it out it ran like crap. Fresh fill and all the problems went away. Ironically my fiance''s bike was winterized the same way at the same time and hers ran just fine on the old stabil gas.
Refill, throw some fi cleaner in and give it a few miles. I hope you're as delighted as I was!
Try some Techron or Sea Foam in the fuel. Follow instructions carefully.

i used seamfoam and rode it for about 30 minutes on the road and maybe an hour off and on just reving it in the garage a few other days combined. this weekend i will ride it for a couple hours on the road and then an hour ride on the highway back home (from it's storage/mod spot). should i keep adding seafoam and or fuel injector cleaner every time i put gas in it til it gets better or run the rest out and JUST put in fresh gas?
Fresh gas is fine. Throw in some premium to bump up the octane a tad. If you want get a hose and siphon it all out. In situations like these I usually siphon the crappy gas into a car where it can be diluted into 12 gallons.

gas was drained, seafoam and fresh premium gas was put in, now only time and riding will tell if it'll snap outta this sickness.
A side note, new gas helped a lot. Iridium plugs yesterday helped a bit more. The plugs eliminated an on-off pulsing I got below 3500 rpm. I did it for good measure, but was pleasantly surprised when it cleared that up.
update: i filled her up with some 93 gas and rode her for about 45 minutes and then BAM my horsepower and torque kicked back on! before that it didn't have the full torque or horsepower and could only get up to about 60 mph. i rode it for another 1.5 hours after that but STILL have that problem when i idle and the 0-2100 rpms, will this too "BAM" and eventully go away with the more i ride you think?
If you took the engine cases and the exhaust off, then I'd double check that the sensor on the alternator side was reinstalled correctly with the original shim because there is an air gap that must be within a certain tolerance for the sensor to read the stator. Did you powdercoat the cases or use a paper gasket that would increase the dimension of the sensor air gap? Just a theory, probably not the culprit but worth checking. Then I'd make sure the exhaust was fitted tightly and the clamps were on snug to eliminate the possibility of exhaust leaks which could make a bike run rough.

i was waiting for someone to mention that sensor and i did ask if it sounded like it could be a sensor problem......i did powder coat the generator case and just put the sensor back in without measuring the gap or anything (and just noticed that it appears to be leaking oil or somehing from the sensor). maybe i'll take that shim off and try it and see how that goes. thanks
