    Thanks, I have serviced the bike, checked all connections, changed the coils around, replaced the fuel pump and cleaned the tank out, also adjusted the bypass screws a bit, as it seemed like a fuel starvation problem, according to the maintenance manual, the fuel mixture gets adjusted by the computer as the engine gets warmer, will this be a too lean or too rich mixture? Is there an easy way to balance these settings with out going to the dealers?

I have to have you start at the basics first on this one. Check the spark plugs, the plug wires, and most importantly, the timing belt tension. Check all connections going to the crank sensor, and also check the rectifier connections and the coil pack connections as well as the spark boxes. Also, when was the last valve adjustment/belt replacement? Usualy the injected Duc's don't ever pick up missfire conditions. The Carburated versions are sometimes known for it, but usualy it's the result of the carbs out of synchronization. I would be willing to say this is a tune up issue rather than a broken part issue. If it were a broken part, you'd be experiencing the issue almost all the time, not just at high rpm's and high load. Check the tune up, let me know if anything looks out of the ordinary in there.

My '98 900 SS ie misses and backfires at low revs, around 60 k/p/h and slower. Thanks.

The engine misses the firing as there is a faulty electrical issue or a fuel mismatch on the settings.
Now if this happens ONLY on the lower RPM,But there is very good performance at higher RPM then it is possible that the timing is set or is offset. It will best to have the engine tuned with the correct timing using the right equipment. Check the engine firing at low RPM Make sure there is no gasket leak on the manifold/exhaust that would change the firing.

Hi, Anonymous the following applies to carbureted also fuel injected models and the usual suspects are:
1. Severely discharged or damaged battery, 9 volts or lower.

6. Failed ignition coil, ignition/electronic module.
7. Failed CKP, CPS, CMP, MAP, TPS, or BAS sensor, corroded, loose or broken wire connector pins/sockets.

¿How much it will be a good price to sale a Ducati 900 SS 2001?

Hi, Joche85 I don't know what part of the world you live in but in southern Florida USA you could get $6500-$7500 depending on condition in the year 2010 for this situation I would call my local dealer or reputable shop's service/parts department and inquire about any possible quick fix, answers, or parts inquiry. If necessary, transport your bike to the dealer or shop and have a professional technician take it for a test drive, if it is in running condition, and give you a written estimate of repairs and answer any specific questions you may have about your problem.

When i start my 900 ss it idles ok for about 10 srconds then the idle goes up to 4000

I the bike has carbs (not fuel injected) then an air leak between the carb and cylinder has developed. This leans the mix and increases idle speed. Usually the rubber parts get hard and then cracks show up, and that is where the extra air gets in.

900 ss Stalling

Sounds like the carbs are getting starved for fuel as load and rpm's increase. Start with Jack's suggestion on the fuel filter and get a new one. If that doesn't do it check other items in the fuel delivery circut. Rust or scale in the tank plugging the pickup dried out fuel lines that are semi-collapsed dirt and grit in the carbs - stuff like that. Fuel delivery problems typically seem to manifest themselves in the higher gears under load. They don't show up in the lower gears when accelerating simply because the bike pulls through them so quickly. If delivery is barely adequate, it has a split second to catch up when you shift. As the duration of uninterrupted load increases, it will run out of gas before the next shift. Typically, they fire right back up after you pull over and let them sit for a minute with the fuel pump running. Does your bike do this?,,,
