Stock harness tape seems to have a low tack adhesive, unlike common electrical tape that becomes a stick mess after a while. I have some 3M Super 33 but wondering if there is something better?
 
There is some heat shrink cloth tape that is specificlly made for use on automotive harnesses. Came out 15 years ago or so. I read about it back then but never tried it. If you find it let me know, I need to do some harness work on my 550.

that's the one I used, and I like it......does not go all hard and crackly, does not become all sticky either, very nice to work with, even after on my bike for a year it was all intact, and where I had to reomove it, it came off nice and clean.

Spiral wrap - every time. I don't care it doesn't look factory, it works.
 
I think the wires would get gooey at 176F. I'd say your good with that.
 
I have always used the 3M super 88. It is a bit thicker and has better cold characteristics than the 33. Wrapped over the old 3M friction tape gives it more stability and is hard to beat.
 
Interesting topic

I have only used standard vinyl electrical tape.

agree that it is sticky, and can come loose,

This unwrapping is avoided by stretching it during application and when the end is reached the tape is cut and another piece is stretched over that end, but wrapped in the opposite direction.

Never had one come undone.
 
Standard electrical tape is designed for throw away temporary repairs and will sluff off when it gets hot regardless of how it is applied. Tapes like 3M Super 33 and 88 are designed for permanent repairs. You will find it in a lot of high voltage applications as an alternating layer and finish layer where large cables are bugged together. I used 33 in electric rooms and 88 in outdoor applications, layering rubber tape that melts under heat, fiction tape for cushioning and 33 or 88 as a finish wrapping, repeating the process as many times as necessary so there was no chance of compression or anything else that could cause a short.
 
I have used Super 88 for years and have been quite pleased with the results. High temp, extra thick, very high quality.

This is what I've used and it works great. Really one of the best tapes to make a harness out of. Especially if they're subjected to high temps.:

I ordered two type of non adhesive tape:

- NSI Industries EWWH 5060 Wire Harness Easy-Wrap - good to 176F

- ElliottTape EE201 - high temp dry vinyl - good to 221F (engine compartment grade). Jim's link above is to a thread where he used ET301, which is 185F tape, so that's another option. http://www.egitape.com/portals/0/Automotive_Industrial.pdf

I'm going to test them against the OEM harness wrap and select accordingly. Will use 3M electrical tape to hold down the ends. Not sure if this non adhesive tape is strictly necessary, but it sure is nice if you have to go back inside the harness and make a repair.
 
I had planned on using EE301 vinyl plastic electrical wrap with 33+ on the ends to keep the vinyl from unraveling. I think I'll pick up a couple of rolls of that EE201 instead.
