You should first download the parts catologue from the ducati site, this will give you a good idea of how everything is put together. I bought the Haynes Ducati 600,750, 900 2 valve manual and teh Ducati 748, 916 & 996 4 valve manual. Don't be scared off from these manuals beccause of there date ranges. The ducatis have remained basically the same. I have a 2002 S4 and my wife has the 620. I have not come across any conflicting data in these manuals, and they tell you how to do things, and save you some bones for other purchases.
Also check out www.ducatisuite.com and www.ducatitech.com for other tech articles. Have fun
That figures..I guess they assume we all have the full set of factory tools. Maybe Haynes will come out with a F.I. Ducati manual before too long. They seem to get around special tools when they can.
Did you notice if the manual said if the sensor monitors temp or barometric pressure?
