I like the idea a of a monoshock, and I think it would potentially handle the best that way, but it would take away from one of the things I like about the old SOHC 750; I like the looks of high quality dual shocks on a bike that it works well.
As for the eletronics, I'm considering using CycleXchange's new charging system that lets you go batteryless, and I'm planning to get rid of all the unnecessary electrics that normally sit between the sidecovers. My idea is to see if any of the parts that would normally be in a Santee box will fit in the space left by the starter. We'll see if that's feasable.
And the oil tank - I've been in touch with John Williams from the Tank Shop about a custom alloy fuel with an oil tank concealed underneath, but he dosn't currently have an SOHC frame to plan the exit points of the oil lines. I think he'll have a frame soon and we'll be in business.
Even though I may not go monoshock, I still want to remove all possble components in the sidecover area. If the Alloy tank/oil tank combo doesn't work out, I'll use the cleanest looking chopper oil tank I can find.
I have a GS450 tank at home to use, as well as swingarms from a ZRX1200 and FZ1. These are the easiest designs I could find to make the same length as the stock CB750 by shortening the front end of the swingarm. I plan to use the best shocks I can get.
Then its 5.5 x 18 rear and 3.5 x 18 front rims on the stock hubs with modern sportbike rubber, CBR1000rr forks and radial brakes in CBR954rr triples, a custom seat, BCR gauge-in-headlight shell, Tarozzi/Tomaselli clipons, custom rearsets, and a custom exhaust.
