Are you asking because you want to know this information, or you have a prize waiting for the correct responder?
1 Were all 69-76 exhaust clamps the same for SOHC 750 9F model excluded on this one)?
Assuming you mean the finned clamps up at the head, they are shown on all the K models from 1969-1976.
2 Was there any parts besides taillight on SOHC 754 that was used on other bikes??
Comparing to other contemporary Honda models I own, the tail light, turn signals (not counting the stalks), grips, control pods, headlight, master cylinder, brake light switches, starter solenoid... (the less part numbers an OEM has to keep track of, the better!)
3 Could you get a Die cast gas cap for a SOHC 750?
If you're talking about one other than the common stamped gas caps, I don't know... The CR750 factory racing kit may have had one.
4 Could you buy a SOHC 750 without a tach (750 Automatic does not count this time)
I don't think so.. again, every "model year" photo of the stock bikes shows a tach..
5 Did all SOHC 750's have a rubber boot on the m/c end of brake line?
They show up in the parts fisches...
6 Did the earliest sandcast 750 have a case protector by the front sprocket??
Yes. I read about company testers complaining that the prototypes would jump the chain if the throttle was snapped shut from full throttle. Honda put the dinky chain guide in there as a band-aid, but in later models the larger front sprockets (improving chain wrap) and better chains eliminated the need for it.
