Loom wrap material - where to buy?

TL;DR: Where can I buy the nylon sheathing that Suzuki uses on the wiring looms? It's a wide sheet with adhesive strips on each side.

So shortly after buying Martin's K6 GSX-R 600, I stumbled across a K7 750 I couldn't ignore. Upon taking it to Mid-Ohio, it seemed the 750 was down on power based off of scientific measurements with the butt dyno. I took them out side-by-side and the top end seemed to fall short, so I started reading various threads here, trying to make sense of what was going on. The bike was sitting for some time with race gas, so the injectors and fuel pump were fouled and I noticed the clutch switch was jumpered out.

After reading https://bbs.wera.com/index.php?threads/07-600-low-hp-need-answers.392560/ along with various threads on gsxr.com and gixxer.com, losing power due to a jumpered clutch switch was very common. I have to say, normally I'm not a fan of AI, but the AI analysis of this problem matched (or at least collated the threads) fairly well and used some fairly technical terms I needed to research further.

With the help of my trusty service manual, I started tracing the clutch switch signal... but it was not obvious to me where the B/Y and B/W wires were shorted. As a result, I had to start taking the electrical tape and sheathing off of the harness to find the jumper. I finally found the jumper, removed it, and am now waiting on a left sub-harness to re-install the clutch-switch. In reconstructing the insulation, I have used 3M friction tape, 3M 33+ electrical tape, and some TESA fabric tape. However, I am unable to source the OEM nylon sheathing material. On some parts of the harness, it was rolled tight; other parts of the harness, it was doubled over... I found it to be versatile and the adhesive did not leave a sticky mess like the electrical tape did. Does anyone have a recommendation for a direct or near-equivalent replacement?

@Michael Bassani @sbk25 thank you for the leads; they are a good source of plastic connectors as well.

I'm looking for a split loom that is similar to OEM; the clerk at NAPA offered plastic split loom (like what you would find on some cars or riding mowers), but I would like to stay closer to the OEM wrap that will not melt or get sticky with heat. Heat shrink would also do the trick if it had a high enough shrink factor; otherwise I'll need to remove termination to get it to slip on and branched harnesses may be tricky.

Right now I am just doing break-fix on the bike; find problem, fix it, and get back out the track. Major overhaul/maintenance will be this winter.
 
You can get that spiral wrap for wires that's good for 280F, its not quite as "sealed" as that OEM thing but its easier to access/make changes with.

Had not considered this previously; thank you for the suggestion!
 
I haven't purchased from here before but high temp (302F) split loom here:

As someone mentioned you can purchase on Amazon as well which I've done before (same 302F rating):

These are the cloth-like loom. Not the plastic-like type.

And then use tesa to tape the ends of the loom, here's one on Amazon:

I think this is the way to go. I have 3M 33+, 3M friction, and Tesa , so I’ll order this material. Thank you everyone for your help!
