Honda-SOHC

Couldn't you just fit a larger head ?

Everything was stripped from the original bike and frame de-tabbed. Everything not necessary, or that could be discarded has been, or has been replaced.
 Hagon have done the rear suspension also a new set of spoked wheels.
 Front end has completely changed and forks replaced with a set of adjustable ones from a Yamaha XS650 with new race  internals. Front and rear discs thrown in favour of new lighters units and waiting for a set of Ducati Brembo calipers to fit I think.

 Engine rebuild is first rate, all blasted clean obviously but completely stripped and rebuilt with everything replaced if it was showing wear. We did give the engine a big bore kit from WISCO to stretch it out to 836 cc and it was gas flow optimised too to improve it a little more. A first class job all round, from a guy called Ash, who apparently is a part-time drag-bike builder. Cam-shaft rebuilt too.

Good afternoon guys,
 I joined the forum a while back and have been simply amazed at the amount of knowledge that the collective has here. A real gold mine of information and very interesting to read though the various posts.

 Unlike a lot of the members here, I have very little mechanical or practical skill, or interest for that matter, to do my own build. I know plenty of friends who are well into years of restoring the same bike and not really closer to an end product. Fun for them but not actually a useable build. so I decided to just pay someone a lot of money and have them build me a bike.
 I chose a CB750 as it was a bike my dad had in the late 70's and I remember it as a young child. And given the history of builds and knowledge out there, I thought you could do a lot worse.

 Its been around 6 months since first discussion with a two-Brother team in Southend called, 'Autofabrica', and we're progressing along nicely with a rolling chassis.

This is what we started with, a donor bike found in Aberdeen I think.
