    There is that.....
    I could mill up a "deck" that could then be tig'd to a milled out engine case. Hmm.......

    Swagger,
    Somebody made a 500 twin that had 2 Aermachi topends laid down on a new crank case. It was raced in the 60's, I think. The builder was Linto? or something like that. He was associated with Aermachi before that. I think milling the front out of a set of CB350 cases and moving the cylinders to mostly horizontal would work, but would worry about the length of the engine.

    AAAAEEEEIiiiiiiiii! A horizontal twim 'Macchi! Exactly what I was thinking of...that's fucking primo.

    I do agree about engine length being a real issue with a unitized conversion, hence my interest in breaking one apart. I can tig up the engine cases to seal the sump, I've done a couple XR250 motors for a dude who makes ultra lite planes. He did all the internal rework though from what I understand there wasn't a lot that needed to be done though that may be a trait of the XR lump.
    I'd quiz him about it but...he and my sister are no longer married and he dunna like me any longer. odd that...

    My thought was that by de-unitizing the engine and trans, one could have a fair amount of freedom with layout. I could stack the trans above the crankshaft, much like just rotating the engine 90* but hopefully keeping the lubricants where they need to be. Plus.....fabricated stuff is just cool....

    Classic Bike Magazine

    August 1997 "Siamese Twin" Patrick Godet's restoration of a 1969 Linto

    Lino Tonti, a veteran of Aermacchi, Bianchi and Gilera, designed a race bike called the "Linto" just before he was
    hired at Moto Guzzi. The engine in the Linto was essentially two Aermacchi top ends grafted onto a single crankcase.

    A Linto racing motorcycle placed second in the final World 500 GP standings in 1969
    1) Giacomo Agostini (MV Agusta) 2) Gyulay Marzowszky (Linto) 3) Freddy Nash (Norton)

    Dick Linton raced a Linto at the Classic Senior Isle of Man TT in the mid Eighties
    and raced Aermacchis in the Junior class during the Seventies.
    He is now a supplier of Aermacchi parts in England

    I found all this a VFT.org/sprint

    A cool site

    Was wondering about that.
    I bought most of the parts to make a V-twin out of Honda XL185 at one time (years before V-twins got popular)
    Lost it all when I moved

    PJ
    I dabble in rocket science, when I\'m not picking my nose
    The other night I gave my girlfriend an orgasm, but, she spat it back at me
