MarkB on SOHC.net and SOOC ( great person has wonderfully detailed resto threads on 750 K0 & sandcasts) asked me to share some wiring material links etc with them on the sandcast site so I have copied the details here for anyone who needs anything. I do have a fair supply of some of the sleeving materials detailed below (NOT SOFTENER OR TIN PLATING STUFF) and I don't mind giving the odd bit or two away but I ask that members have a few postings under their belt before asking.. there are a few lurkers out there and we need regular contributions from everyone as it enriches our knowledge base on here, in my view.

Re: The Wire Harness Thread - Everything About Repairing, Restoring & Replicating

I need a little time to get my facts together Mark but I will look into cleaning up the old connectors in Ultarasonic cleaner, softening the old PVC covers etc.etc.
Vintage Connections are anyone's first port of call because they stock the correct bullets, multi-block Hitachi non-latching connectors, crimp tool, silver-grey sleeving for the starter solenoid etc. Nice family concern to deal with .. but high import duty for us in the UK.
http://www.vintageconnections.com/I seem to remember my K0 main loom was made by Sumitomo. ( each coloured wire is marked with Sumitomo 1969 ..cool ! )
Here are my sources of other stuff:
Tinning solution ( not tried this as I have old stuff that's great but NLA but it should work if the surface is cleaned and degreased) . This is used to replate bullets/receptacles/components etc.

The grey is also used on the oil pressure switch cable plus woven glass sleeving.
Vintage connections sell the non-adhesive, black PVC loom tape or it's freely available on eBay.
NEED TO FIND : The thin walled nitrile rubber sleeving for the alternator sub-loom and the HT leads covering. It's around 1mm wall thickness. I do have a lead on it though. Plus the 18AWG glass/silicone woven single cable, in the correct colours, for the alternator coils (high temperature as used in cookers). The same wire is also used on CB350K/CB250K twin, points loom but I think the 750K0 used high temp. PVC yellow and Blue, which have a source of from' Alpha wire' in the US
RUBBER SOFTENER: Needs to be immersed for a long time (overnight) at 70 degrees C and I think it will only work on Nitrile rubber not PU (Polyurethane). I had an original '69 46k mile inlet rubber and airbox 'rubber' from my 10/69 K0 analysed and the result was that the inlet was Nitrile & the airbox was PU. This softener definitely does work, I will post pictures of before and after and the part was treated in 2011 and still soft and elastic but it needs long immersion at highish temperature ( I use an old 'slow cooker' to heat the softener in a glass dish water bath .. if you get an invite for dinner at my house .. then gracefully refrain Grin)
http://www.greatlakes.com/Industries_We_Serve/Building_and_Construction/Other_Building_Materials/Reofos_50TRY NEWARK IF NO FARNELL STOCKIST IN YOUR REGION for sleeving etc.
MARK PLEASE PLEASE DON'T BUY ANY OF THIS I WILL SORT YOU OUT ENOUGH FOR A COUPLE OF BIKES AND POST IT FOR FREE TO YOU>>> I OWE YOU ONE !
I will do some more investigations on the fused clear covers and post back. I am sure I can 'crack' it.

REGARDING CLEAR PLASTIC FUSED COVERS ON HONDA BULLET CONNECTORS.
"Mark I remember a post where a member replaced the insulators on his harness. He sealed them to the harness by using one of his wife's or daughters old hair flat irons I believe it was. Through trial and error he carved the shape he needed into the flat iron heating pads to make the correct looking crimp. (Melt) I'll keep looking for the post".
"
It was ashimotok0 and he did make it from his daughters hair iron."
REPLY B ME:-
Yes it was me and I did make the fusing tool from a pair of my daughter's old hair straighteners. The problem was finding the unplasticized plastic clear sleeve. I did find some at a works Chrismas party used for inflating those squeeky ballon thingy's. I went round after the meal collecting everyones unused ones. They are probably unplasticised for safety reasons.
I need to revisit this because I fell ill after that original post and chickened out and used the Vintage Connections sleeves (see attached) but you have rekindled my enthusiasm Mark for my CB350K1 / Cb250K0 wiring loom restorations.
I also used the tinning solution for re-tinning the old connectors and plating the bare brass ones from VC, the type of solution you use for making prototype printed circuit boards (PCB's).
