Greetings fellow Honda fans. Hope everyone is well.

I've stalked and lurked on here for ages, Finally got round to writing up what I've tinkered with.

It started out as a little bit of fun, I went to Cadwell Park for the international meeting 3 years ago i think it was.
There was a George Beal Honda 6 replica there, Along with all the other iconic race bikes. This really set the wheels in motion.

I really wanted something cool to ride about on and just generally play with, So i sourced the project, Luckily there was a race bike that was nestled away in the back of a gentleman's shed, After a little negotiating, We brought her home!

Then the fun started, Stripped down and removed the bits i didn't require.

Just a few pics of the progress.

I shudder to think what i have spent on it up to now, However i'm pleased with it, There is still some things that i want to change on it before i feel like its complete.

I recently had it on the dyno, A cheeky 49.8 Bhp. Which i'm pleased with, Still needs a little more jetting though.

I do have a clip of it running and on the dyno. I'll try and post them next.

Very cool build!  The front brake is amazing.

My buddy Charlie built a similar replica.  A very neat machine.

It looks very nice.  What did you do to increase the engine power?

Cr26 carbs / Yoshi 460 kit & a little skimming and a lot of fettling ;)
