    Boy, you wait for the questions about this project when I get started on it...though it will probably not be for a few months!

    I'm expensive. Tech info goes for about Oh how much is a dry clutch....
    Have your heads got hardened exh valve seats and modern valve guides? Might as well before you slap it all together.

    To be honest I don't know, the engine is at the builders getting finished...but I shall enquire when i speak to him next.

    When I bought the project included was the offer to finish the build of the engine, which I took as I thought that it would be better than me just getting a bit over my head on this one as it is none standard.

    The engine spec includes the following;
    complete 'V2' crank
    'V2' clutch, primart gears and L/hand case
    'V2' selector drum
    'V2' breather tower
    'V2' sump strainer
    as well as some 'V2' gearbox parts and other modifications.

    I really don't know alot about these bikes but I have been lead to believe that it should give me an interesting track tool!

    Off Brook, good well he's back in business doing bevels again, so any complaints can be addressed should they occur. Not much to know really. don't go above 8k rpm and all should be fine. Check valve clearances at 10,000 km and pull heads off at 20k. Mine is referred to as either the dinosuar or the plank for reasons that will become obvious as soon as you get on it and go. Be prepared for a work out.

    I rode a BMW K100rt and K75rt in the three years that I did courier work around London, I know what riding something that is heavy and wallowing is like...can't wait to have a go on that 'plank' of mine though.

    I think I had best get myself something cheap to do some track days on as I have never been on a track, I think I best start slow. Perhaps my Kawasaki gt550 would be a good start, lovely shaft driven bike...good for abusing and doing courier work on. It would be fun doing a track day on that to start with, especially adorned in full one piece 'Biaggi' Dainese leathers!

    PS Steve knows sod all about these as he is stuck in prehistoric 4 bolt disc world. Anything bevel with 6 bolts discs is not a real bike in his world.
    So how do you know it's a Mille "Smarty Pants"??
    The 1st models with that shape/type of LH engine case were 900's, still with a needle roller bigend, looking at the cam support blocks it looks like one of those to me, the frame looks like a chopped about standard one to me,
    NCR never used bolt on bracing or the 2nd longer brace, but as you say I know sod all.
    I agree with the rest of your post though.
    On another note the S2's came with either an electric boot or a kickstart and were a very watered done version of the real thing, better than a Drama but not as good as an SS.

    Peter,
    They don't have to be a plank to ride, I've got Maxton modified forks and Fournale shocks and it's quite supple

    Steve, most of the bike has raced in previous incarnations though I believe it never managed to race in the form that I bought it, I dare say that it will handle much better than my ability...I know that the forks were reworked and the rears are Ohlins, almost nothing can be as bad as a BMW K100rt with a wallowing rear shock!

    My project is a true bitsa, an amalgamation of parts from all over the place, Having checked the engine case numbers it started life as a 750gt, but virtually nothing is standard. I doubt the heads or barrels were even the original ones that came with the cases...it has had much work and money spent on it by the previous owner.

    Hi Peter,
    Who race it when it was fitted with the mille engine ? was it raced in the BOTT uk series.
    Why i ask is my Dad owns a MHR mille and we used to watch all the bott rounds and a few raced mille dukes.
    I even remember Glyn Robinsons jawa headed 900 bevel engine

    Steve, it was campaigned by Geoff Baines during the 1989 season I believe, but I am unsure of how successful the bike was in that form. I would be interested to know if somebody could furnish me with any info, thanks in advance.
