These have been around for years, I've always found them very good.

Used these people several times.......excellent !.

I too have used them and found them to be excellent. If you are close enough to them to visit you will find them very helpful as there are a few bikers amongst the staff.
As for any advice regarding the rewiring
1) Take as many photos as you can of wiring runs on the frame
2)Get a wiring diagram for your particular model.
3)Take your loom off the bike if possible without too much damage and lay it out as flat as possible to make it easier to copy.
4) Keep to the original colours for future reference.
I m sure other people have other advice but this has stood me in good stead over the last 15 resto s

Aye Brian,
Fully agree with all the tips that have gone before.
Personally, I would solder and use shrink tube wherever possible to keep the terminal joints secure and corrosion free. Also invest in a pair of self-adjusting wire strippers they really do save a lot of hassle and make the job less vexing. The TT45 on the VWP site works well.
Italian bike ownership has meant that I have used these people and methods 'quite often'! ;)
All the best, Bill

I would not bother,unless you got too much time on your hands. My loom was shot, bought a 2nd hand one for about £30 from Germany. Just take note of route on the frame,( draw it out), and mark up where every connector comes from. If you must build one, don't solder, its makes the copper go weak, and buy a really good crimper, not Christmas cracker quality, good luck. Vehicle products are excellent

i would have bought a new loom.it would have been as cheap if not cheaper to do so. unfortunatley,if you can find a nos loom,they are already over 30yrs old. the same goes for secondhand.one good thing is i am really getting to know the bikes electrics and yes its very time consuming. am treating it as therapy ::)

I've been soldering cables for well over 40 years and never experienced this......
I actually enjoy rewiring especially when using the proper cables, connectors etc. The problem with reusing old looms is that the wire has often corroded under the insulation making connections a bit iffy. They also often seem to be full of filthy oil - I have no idea where that comes from.
Whatever you do don't use those pre-insulated crimp connectors. VWP do a nice range of connectors with flexible vinyl type insulating sleeves. They don't do decent multi-pin connectors though.

A job I am looking forward to tackling on my old Beemer in due course. New looms are unavailable, this is going to have to be built from scratch.

get a big board, lay your loom out on it, it helps if its warm cos its more flexible, mark out the connectors on the loom and fix them to the board. then lay the loom out in straight lines , if you can, secure the loom down to the board with nails hammered into the board and loops of string tied round the loom. photograph everything. once the loom is layed out, carefully remove the insulation from round the wiring. write on the board an identification for every connector, abc, or 123 etc. then take notes of the wires from each connector colour, length and destination etc. then, assuming you have all the correct connections and wire codes as well as the correct crimpers, then remove the loom, and starting wherever you want lay your new loo out one wire at a time till theyre all laid out on the board, then crimp the connectors on and insert into the terminal blocks, finally, wrap it with the correct wrapping. (or thread the wires through the correct sleeving before crimping them up.
doing it this way has the advantage that you can walk away if you cet bored and come back to it without losing your place. its also worth remembering that if your bike is a bit rare, and its standard, then buy enough materials to make 3 or 4 looms up. and sell the spares on to cover the cost of making them. you should be able to get your own loom for free if you do it this way by selling a few spares.

I'm covering an existing loom, as its currently sheathed in gaudy purple plastic. I ordered some black wiring loom tape, which arrived today, but its very BRIGHT AND SHINEY! Would I be better using the black fabric Tesa Tape, I see advertised?
-
It soon goes dull. It's much better than using adhesive electrician's tape throughout (although I always use a bit of that to secure the end, stuck to the harness tape not the wiring).
I haven't come across TESA before but a quick google seems to show that it has an adhesive side.
-
Thanks Ian, I'll get stuck in with the tape I have. Its supposed to be proper loom tape, and has adhesion to itself, but isn't electricians tape, which I will use at the ends as you suggest :)
