They certainly are ;)

So the build is progressing slowly.
I am currently searching for the following:
- CR750 original style tank strap.
- CR750 RC seat (not sure about the meadspeed unit)
The fueltank is strapped into place on the rear of the tank only, the front is held in with rubber mountings. Unlike the Yamahas which are often strapped front and back.
The difficult thing is getting hold of a ‘replica’ fueltank strap to be able to do the tank justice! I could use a Yamaha part that would work well, but I would rather not. Just to add detail to the build and some originality. The only thing I don’t like about the RC style strap is that the bare steel loop of the strap sits onto the aluminium tank so I think I may have to sheath this somehow. I can make up the stainless parts by hand bending however the challenge comes with the rubber part!
Stock extrusions exist but after quite a bit of research there is not a suitable stock part that I could use….
This type of part would have been overmoulded over the wire sections, which is expensive. As well as moulding, extrusion is an option for manufacturing this part however again there is a tooling cost associated with this, and it is high as I would only want a very low volume of parts.
A company named ‘CR750 RSC - Works Motorcycles & Parts’ who I came across on Facebook make a replica strap that is close to the part that I am after however I would like a go at making one myself. Some of their other products are fantastic including frame kits and machined parts – well worth a look! This is the replica strap available, similar to what I would like to achieve:
I have ordered some stainless bar to have a play with bending it, I also ordered up a few Yamaha straps to see if any of them are close to the part I am after and could be utilised/modified. When I get fed up of trying to sort this out I will just order the available part and see if I can tidy it up?
I have some time booked off over soon, and I intend on building the twin disk front end up, de-lugging the frame and adding the seat and tank mountings so that I can finally look at the tank on the bike and get stuck into the project!
Cheers!

Here is the twin disc guide that I used, I found it a very easy job, people on various threads in the states seem to struggle, not at all sure why, maybe we're cleverer than our Yankee friends? 😄, make sure that you use a master cylinder that is designed for a twin disc setup, i used one from a 97 fire blade , works well but maybe wouldn't suit your bike as I think your going for a more original look, GL1000 master cylinder may be better for you, yes the mead speed seat looks nothing like the original, I used it because I needed somewhere to hide the battery, the original CR had a tiny tail cowl.

Hi Mark!
Thanks for the link, I have already linked from a thread from this forum (may be your build thread) its very useful. That may be the case ;D
Cheers for the heads-up on the master cylinder, I was planning on using a GL1000 one.
Tricky one the seat as I am after one with a cover/seat swab as trimming can soon get very expensive! I have a Meadspeed unit that I picked up but I am not sure if I am going to use it.
What ignition did you use Mark? I was thinking of using the DYNA total loss system.
Cheers!
