That's great advice. I'm already cruising the Ebay
You got it. The tank and rear tail are both airtech
The forks got a complete overhaul with bushings new, progressive springs and racetech emulators.......fork seals with new fluid. I can't really remember the preload but the feel is great yet still that old CB feel

gonna have to disagree with Geeto on the 77/78 carbs as there are few tuning parts available, the accel. pump is very expensive (and difficult!) to get working, and even more difficult to keep working in the ethanol age. Without the accel. pump, they are lean burn emissions era garbage.
The stock 75-76 use the same parts as all other years of sohc 750. They are stone axe simple and contain no o-rings to constantly need replacing. They can be torn down, cleaned, and adjusted dozens of times without needing a single replacement part. Many services don't even require removal, as the float bowls pop right off with just a spring clip holding the bowls on.
Progressive spring winding doesn't work well with the emulators...standard winding much better. Your spot on on that.
I've purchased racetech springs a handful of times. It's always progressive for me but it very well may have racetech standard winding springs in it. It looks as if one of the fork seals is leaking so when I tear into it to repair I will know!
I dunno, my 1978 F always rode better than any of my round top cb750's specifically because of the accelerator pump. The secret to keep it working in the ethanol era is to ride the bike and not let it sit longer than a week. then again most of my riding was in a city environment with lots of part throttle and sudden bursts of acceleration. YMMV. I like the accel pump 77-78 carbs, others value the simplicity of the round tops. Personally I'd shitcan both for a set of kehin CR's but $500-700 is a lot to spend on carbs these days.

Or spend the time searching for gas stations that sell non-ethanol premium, avoid the ones in shity parts of town and pay the extra $$ for it. Honestly I hate ethanol, I have yet to see any real benefits aside from keeping the environmentalists happy'ish. I notice worse MPG and decreased performance. So with the lesser MPG, I am at the pump more often and spending more money in the long run. I did the math once, at the time it saved me like $400 a year to use non-ethanol premium in my truck instead of regular.

if you want any of our parts that are being ebayed ill pull the listing and take off 15% right off the top and some more discviount kicked in as well
i cant be falling in love with a jillion parts
but you can bet i am gathering a collection of cool bits to build some tricked out scooters
i want to build a 2 t twin,in design similar to a rotax tandem
but a a 375cc usung a 125 and a 250 geared together
dont be a fool and say it wont work fact is it will work spectacularly well
the 2 disimilar power bands will complement each oither and wont it sound lovely ?
especially with the lashup being not one tgo one but geared logically the c125 spinning maybe 10% faster maybe even varible pitch fluid coupling with loickup clutch or a very close ration 2 or 3 speed geared couplng with programable lockup and overun clutches
right then 2 gearboxes final drive and a coupling gearbox
why has this not been done ?
oh yeah with variabkle crank fazing as well
big bang lag bang bing bang bong
