Hi, new to this site but not new to owning the CB750 sohc. Got my first cb750 about 1980, had an 810 kit, got another one from a friend in 1986 for £250. It's an F1 P reg. I soon started updating it, first was F2 tank, forks etc and comstar wheels and CBX1000 discs/calipers (I used to visit the breakers on a regular basis, we all like a bargain)
This is how it looked in 1989 in the south of France

This is blasting round the Paul Ricard circuit in South of France

Then a year or 2 later it had it's major makeover, while in allbike spares I spotted a Seeley petrol tank, brand new and they only wanted £25 for it...done! had a bit of messing about to do to get it to fit, also got VFR750 17" wheels and brakes, dug out my old original Yoshimura pipe with home made baffle. I also did a lot to the engine, 823 yoshi kit, gas flowed head (early head with larger valves), lightened/balanced crank with aftermarket con rods, i think they were action 4's, also high lift cam and stiffer valve springs, also got a set of GSXR750 flat slide carbs which were a nightmare to get the jetting right, trial and error for 2 months!!
End result was quite remarkable,it now revved to over 10,000 rpm and i saw 145mph many a time,(probably would have pulled 150 i'm sure) but the speed it accelerated, nothing could touch it up to about 90, thats blades, zzr11's gsxr's...it was hot! I shocked a lot of people at bovingdon aerodrome!!

And it even handled now with the 17 inch wheels and radial tyres
It wheelied like a nutter too, i had to put the original swing arm back on because the braced JMC i had cracked around the chain adjuster!!

But as i said earlier, it has been standing for about 13 years!!!

Bit of a sorry state, but I am determined to do something with it next year, there was something really enjoyable about beating new bikes that it simply should not have done :)

Really interesting, it's good you got some pictures of it over the years and those Yoshimura pipes have the best looking shape of anything available for the 750SOHC.

Like the Jeans and trainers on a racetrack too!! what style.

Are you going to try a build up as in it's heyday?

Super nostalgic pictures. Love the transformation.
The bike definately deserves a bit of TLC now.
Should be fun
