CB750F2 .... silk purse from a sows ear.
SumpMagnet:
Damn ... has it REALLY been this long? Got side-tracked by a Triumph, work, life, stuff ... but having got the old Triumph to a certain point, I felt it was time to give this project some time.
The parts search turned up a nice set of exhaust collets and finned collars. Both things I was missing. Then an exhaust. One of the MAJOR things I was held up on. Picked up an old unbranded 4-1 straight pipe system that isn't rusted out, and even has chrome that is almost presentable. It's probably going to get painted as I suspect further issues trying to shift hte baffles, and the header pipes are glued into the collector with exhaust paste. No idea if they will come out, or if I should even try.
The pipe sits tight up to the bottom of the engine, looks like the centre stand can stay, and sits nicely. If I have to gut the baffle and make a new one, then I will.
Then I actually got around to cutting out the footrest brackets. Blunder was made with the spacers I had the old-man make on his lathe. Fractionally too wide. Might have to cut them down....or..take them down when we go to visit in January, and turn about 5mm off each one.
Going to mock up the parts and take some pictures. Just to keep me motivated!

You are back on it, that's always the difficult bit👍. I think I'd leave the exhaust as it is as long as it looks decent and can be painted. Separating it may create problems and probably won't achieve anything anyway apart from potential grief!
SumpMagnet:
Here;s what we got done... The rearsets are off an old CBR600, and were a bargain. The brackets to mount them are carved from 10mm thck ally plate. Possibly a bit overkill, butI needed to make up the space of the old footrest hangars, and it gave more meat to cut the threads into to bolt on the footrests.
The exhaust looks like it clears the centre stand, and sits in nice and neat. I was struggling to find a pipe that I liked, and this was just £75 on E-Bay. Some surface spotting ( most of it isn't rust...just muck and rubbish. Some rust, and a few rusty patches around the tops of the headers. Most of it will clean up, but I still plan to give it a coat of black gloss exhaust paint.
Got some spacers turned up to take up the slack and some stainless engine mounting bolts, with the rear one shorter to fit with the hangar plates.
Still lots to do, but it is taking the shape I had in my mind , which is good. Paint .... going to go for red, with the black stripe and white pinstriping. Want to go for something similar to the dark red I had on my 900 Hornet, and will have the side panels black.

That's starting to look really cool, I like the rear lamp fitting, it looks like it's built for speed when standing still.
SumpMagnet:
Thanks :)
The rear light is a motocross unit, on a cut and modified plain steel mudguard., I welded a couple of mountings to it to hook the mudguard up to the mounts on the end of the seat rails, which double up as indicator mounts. Then the light just bolts on top. Seat is a CR750 pattern fibreglass unit. I made my own hinge and catch setup to it fits to the stock key operated latch and hinges open. I didn;t want to make holes in that lovely curvy hump to put lights in...so I went for something that blended in and still had a period feel.
I wanted to get the feel of a CR750 kind of era bike, but I don't have the budget or skills to build an actual rep.
