I recently tackled the clutch on my bike which was old and beat up... put in a new basket and plates as well as a Vee Two hub, a pressure plate and a new slave cylinder... i can say that it is way sweeter than it used to be when it comes to shifting...but my new problem that has become a concern is how rough it seems to ride...it seems to bog and buck when i am cruisin around town at 25 in second... but this isn't my biggest concern its the fact that when i ride her hard and the engine is hot sometimes when i come to a stop in nuetral the idle will stay around 2300 rpm for a little while...it seems to stick open.... then it will fall back down to the norm 1200 range...but then some other times that are more rare it will idle down to the normal level after driving but then it will start to creep up until it reaches that 2300 rpm area and it will stick there... and i never even touched the throttle... does anybody know what this might be... i am guessing the carbs are the problem but i am new to carbs and i don't really know a lot about them...
i don't understand what a lot of the terms really mean... but i am willing to learn...
Check for vacuum leaks, synch throttles and make sure the idle is not too high (below 1300 RPM hot)

If you've got a minute and don't mind running through this at some point, I'd love to hear about how this went - was it difficult, how long did it take, what parts did you choose to leave stock and why, etc...

Gotta ask a few questions first-
Carbs stock, upgraded, or jetted?
Pipes stock, performance, cored, etc?
Air box- stock, carved?
Hi-flow filter / pods, or stock?
Stock plugs / coils / wires?
May be carb, but there are several things that could be leading to the rough ride.
I got my '96 M900 w. the stage 1, carved box, K&N and cored pipes. I took it on with the statement from the previous owner that it "surged" at highway speeds and that he couldn't seem to tune it out of the carbs (he recommeded I track down a set of flatslides... for 'bout $800. Riiiight...). Anyway, I never really noticed any surge at 65+, but I had the low-speed lurch that you talked about. I never did monkey with the carbs, but I replaced the beat-to-shit aluminium rear sprocket (with two broken teeth), the shot chain, the worn-out drive sprocket and the whole cush drive this winter, and what I thought was a fueling problem seems to be completely gone. So the bogging could be fueling, but the bucking may be coming from a drive train issue.
My $0.02. Please bear in mind that I know jack shit about fixing Ducatis.
Good luck.
No problem running through it... the job is suprisingly very easy...all together it took me about 1 1/2 hours to do, might i remind you that i am new to ducatis... i had only had the bike for a month when i did this...it is one of those jobs any body can do...
You start by removing the 4 bolts that hold on the stock clutch cover.... thene the 6 bolts that hold down the pressure plate... after this you will be able to easily see the condition of your clutch pack.... i originally did this job becuase i wanted to put just a pressure plate on with a clutch cover... you know, cuase it looks cool....but once i got to this point and looked at my clutch basket and the clutch pack i decided to do it all....
To get the basket off you remove the hub which is held on by a 32mm bolt that is on there pretty good... i had my buddy sit on the bike i put it in 6th gear and he held down the brakes... probably not exactly the right way to do it but i got my nut off [thumbsup]
from this point you can pull the hub out and it will expose the 8 bolts that hold the basket in place...they are locktighted and will take some effort to break lose.... but after that is out you have a clean slate and you can start by putting in the new parts... I replaced everything except the bolts... I put in a Generation 2 Procutting Hard Anodized Clutch Basket with Barnett plates with the red friction material from Desmotimes, a Vee Two clutch hub i found on Ebay... a Desmoporsche Pressure plate from ebay, TPO RACING Stainless Steel Clutch Springs and a clutch cover i found on ebay from Europe somewhere...
This job was very easy to do... the parts are the hardest to get... i replaced everything just for peace of mind, plus i read reviews on the different items and finally decided on these parts.... i like to make sure that everything is in good condition on my motorcycles, plus it was an enjoyable job becuase as soon as its done you can realize the results.... The bike seems to rev easier now and the engagement is very smooth...no more grinding noise... plus the ducati "sound" is still their but now i can also hear my exhuast note too....
After this was all done my clutch pull effort seemed to be a little more than normal...not much but it was there. i attributed it to the new springs...so i decided to replace the slave cylinder with an Evoluzione Brand Clutch Slave Cylinder... which helped out a lot.. came with instructions... it took about 45 min to put on... bleeding the system took the longest... but after this install the clutch pull is much lighter and i still have a very solid clutch feel through the lever... this mod brought the hole job together... highly recomended... the only parts i left alone were the push rod and the clutch master cylinder... everything else is new and i am damn happy i did it...
Cost- about $650 all together- almost as much as a slipper clutch but i didn't want a slipper clutch....
there you go...hope this helps
now back to the oriinal problem...i had thought about replacing the chain and sprockets... i wasn't sure if this would cuase the surging but after riding yestersday and listening very close i think i hear some noise coming from that area plus the teeth look beat to shit... it might be time to fix that set up... we will see...
