The 748s, 998s, older Ducatis always had a fast idle position on the twist grip. So they would have a faster idle when in a cool/cold motor state. Kinda handy. The 848/1098/etc models did away with that feature, going instead with an electronic idle control feature. Prolly something to do with emissions control or whatever. Anyway, after a little weight trimming, I acquired a billet throttle body bracket to replace the stamp steel piece of shit. Lo' and behold, no provision for the elec idle control, after some information gathering, I plugged the hole in the airbox, plugged the holes in the throttle bodies for the hoses, and did away with all that stuff.
Now hear is where we get back to the OPs question. Yes, you can adjust the idle control on the throttle bodies! First, mark the positions of the OEM brass screws, they are the big headed ones on the right side of the throttle bodies, turn each equally counter clock wise to increase the idle, I would suggest a 1/4 turn at a time. With the idle stuff removed from my 848 motor, I ended up 1 full turn from the marked spot on each throttle body. Bingo!! The motor idles perfectly when it gets warmed up @ about 1200rpm, and I can let it set there under a very smooth idle, again, after the bike temp is about 120+/- deg. The only time you have to sit there is in the beginning of the start up cycle. and I saved a bunch of weight, up high under the tank. As it turns out, the electronic idle control is only for cool/cold starts, and activity under 4-5k rpm. So street riding weight is not much of an issue, race bike, different story..... take care of the ounces, the pounds will take care of themselves. Just sayin. Don't be afraid to experiment with your bike in a controlled test, it is fun stuff. And, of course, certainly don't believe all the bullshit you read from folks on the internet.
