The bike look good.
CB750 SOHC is for me a special bike since I have own mine since I found mine in the shop january 1979 in absolute standard shape except for one dent in the tank and small cracks in sidecovers. It has a special place in the motorcycle history too. It look good as it is, no big changes needed, maintain the CB750 look is better. Other handle bar is OK as well as repaired engine with more power
If I should buy a CB750 today I should buy as original as possible with 4-4 system which today cost a lot. Tank is possible to buy new, old tank with side covers need probably new paint anyway and plastic side covers cracked as mine were 1979-1980.
I have changed my mind since early 80's when modifing the bike was obvoius every winter. Longer fork, not standard paint, 4-4 exhaust heavy and awful, 4-1 was much better, tuning the engine.....
So, my bike has last year got new tank with side covers OEM style, new paint with all badges, trims AND new 4-4 exhaust waiting to be installed when I have it running perfect and no need of lifting tank every 2:nd week. The engine will continue to be tuned. I destroyed the look back then, now I have to repair my choices which were really fun over 30 years ago.
When looking at all parts available and forum, I'm not alone thinking and doing as I do despite all $$$$ spent and more to come
DOHC CB750 can be found here for really small money. A 1978-1979 in perfect shape can be found for $2000US while a good and complete CB750 SOHC K1-K6 cost tripple, K0 even more.
It's CB750 K0-K6 that are special as well as Kawasaki Z1 900 and Z1000 1977 in my mind.
