Thanks Paul! Hi Graeme, good to hear from you. Yes, I noticed that compression release and thought the same thing! That's a great question, what is a real TT1/TT2. Some TT2's had numbers, others didn't. TT1's even less. The best way is probably history, not always the easiest thing to find out. When was it bought, Some say NCR built all the TT1's and a lot of what people think are real TT1's were kitted TT2's. Even the factory racers. If you look at what would be considered a 'catalog' TT1, it should have an NCR dry clutch, 16/18 wider Marvics or Campy's, with the QR rear wheel, different exhaust than the TT2, still a two into one but routed differently, Obviously the bodywork is different, a battery tray on the frame versus the battery in the fiberglass seat of the TT2. Most all TT2's had the Marzo 35mm front end with F05 calipers and 280mm rotors, the TT1's, which very few were built could have 35,38, 41.7mm forks with F08 calipers and 280mm rotors, even some with P432 calipers. A few factory racers had RGB 500 Suzuki 40mm forks. Reno told me Cagiva modified 3 sets that were in the States. They all seem to have the Pulsar rear shock, same electrical panel, Verlicchi clutch lever without the mirror boss cast in (TT1), plastic Verlicchi throttle without switches, some people switched to the throttle with the cutoff switch as it is required here in the states when raced. Engine internals are also a big thing. Sadly a lot of these original motors were blown up. Some early bikes had sand cast cases, usually the factory bikes, but I believe they went to production cases later on. I have the original set of sand cast cases for my Adamo TT2 in the garage, blown up and rewelded. If you look at the Walter Villa bike that was on display at Assen you can see the welded cases by the bottom pulley! I've read they only made the TT1 in 1983, but NCR had one at the 1985 Milan bike show and the bike I just purchased may have been built in 1986! Sorry that I've gone on so long, I guess what I'm trying to say is that finding out as much as you can about the bikes history should lead you back to NCR or the Ducati factory. As well as components used and a bunch of small things I'll take pictures of and post them. My red and silver TT1 is buried in the back corner of the garage, I will take it out and try to show some comparisons with the 'new' TT1 I just bought. The some of it's parts and it's history, that is the best way I've come up with. I am sure others have there own thoughts. Lou
