Hi,
The bike looks fabulous well done that man!
I have a couple of questions.
Are the exhaust pipes linked/ballanced behind the motor?
Did the system come from Mario Sassi/Old Racing Spares?
I have a 900ss based special myself, so I know how much work went into yours.
I've owned mine for almost 29 years and it's been a continual process of modification, I've covered over 130,000 miles on her, I'll be taking her to next years Isle Of Man TT races as it's 3o years since Mike Hailwood's triumphant return on his Sports Motorcycles entered NCR.
I was there when he made his comeback (on my "74 T150v Trident) next year I was there on my new 900ss......
I was only 22 years old, it was my 5th TT visit.
Steve, you are correct the pipes are from oldracingspareparts, and they have the link pipe. The bike seems to run better with those rather than the ncr 2 into one that I also have.
I would really love to go to the isle of man next year, it would ne amazing to do a parade lap on the bike.
How many times have you split the case on your bike?
I have another rolling chassis with an 860 springer motorthat I am doing up as a street bike.
I piuchased a bunch of ducati moulds and one of them was the one for the 1979 and later seat and tank. So I will do one for the street bike.
Thanks for the comments!

Huit,
How many times have I split the cases on my bike?.....
I've lost count as I've done it soooo many times!
I've run lightened cranks, plain bearing cranks and now I'm running a standard weight ballanced crank fitted with Carillo rods, INS needle rollers and extra thick HD thrust washers, these needed the crankshaft half's machining to fit.
I also run a lightened/smaller flywheel with narrow straight cut primary gears and a dry clutch.
The rest of the motor is quite heavily modified, but I recently reduced the capacity and comp' ratio from 950cc 11.2-1 down to 882cc 10-1 along with some other mods, in the interest of longevity.
The 950cc balls out motor wouldn't run on pump fuel here in the UK anymore, despite using twin plug heads with the ignition set at 28 degrees fully advanced. I reshaped the combustion chambers to suit the bigger bores and 4mm oversized inlet/exhaust valves.
I had to use a mix of AV GAS and pump fuel! To avoid detonation.
The 882cc motor now runs pump fuel +2.5% pro boost, (alcohol based octane booster) 35 degrees advance with no detonation.
It's not as fast but hopefully it will last a bit longer.
My bike doesn't look anywhere near as trick as yours, but it's won best Ducati here in the UK more times than any other Ducati. I took it to the WDW 2000 event and it was featured in the Italian Cafe Racer Magazine as "The Sprit Of The Desmo", she's known here as 'Beverly'.

Steve can you send me some info on the cranks, I have some 92mm ncr cylinders and pistons I would like to use in another motor any info would be great .
thanks paul duc748_sp@yahoo.com
Every time I see something like this I wonder if I could learn to work on a bevel drive engine. Purposeful, and Beautiful.
Sure you could! Buy yourself an 860 (roundcases are getting expensive), join the bevelheads mailing list, and get on with it. I did that with a 750 GT and it's pretty much responsible for bringing me back into bikes after a couple years of little interest. Now I've got four vintage Ducs as I've since picked up three single cylinder project bikes.
I've got to disagree, if you were going to use Mike's number, you'd need to use the Sports Motorcycles Red White and Green paint job..........
Not the Italian flag, but the colours of his main sponsor Castrol.
Anything else wouldn't look right IMO.
I rather like the original NCR colours of Red and Silver myself, I saw these bikes raced in Europe in the late 70's and early 80's in the world endurance championships.
They outdragged the Sonauto TZ700/750 Yamaha's on the Mistral stright at Paul Ricard for the 'Bol D'or', the sound of the thundering V twin against the screaming 2 stroke had to be heard to be believed!
I stood in he pits marvelling at the dry clutch on the NCR's, thinking I really want one of those..........
20 something years later, I finally bought one at the WDW 2000, a friend commented that he'd never seen a man get so excited over a piece of metal.
The man has no soul!!!!!
My idea was to make the bike as close as possble to an original NCR, the Hailwood bike was a Sports Motorcycles Bike.
My choice of colour was based on the fact, that you could tell it was an imposter!
It is close!
