Wiring on K0

[AshimotoK0]

Anyone know how many dark green wires are in the main loom which going into the headlamp bucket on a K0?  I suspect two, which each go into multi way female bullet connectors.

found this which is really good

Anyone got a hi-res picture of an unmolested K0 loom?

As you can no doubt guess I am currectly rebuilding my original loom

Can't guarentee this, but I believe the K1 and earlier had the same loom. The only changes between the two were the air boxes, the side panels, the carb linkage and some other minor bits. The wiring was exactly the same, so your K1 diagram should be correct.

Do you have a copy of the early manual? if not I can post a copy of the diagram.

Hope this helps, but I suspect that you know most of this already.

Just checked the part numbers on Motogrid. K0 and K1 have the same number

32100-300-050

Thanks - I have the manual just wanted to see what it looked like unmolested.
 gues this pic gives me a good idea!

Hey - just looked on CMS website at the feedback on a new K0 wiring loom (actually a '341' loom) and someone complained that the twisted and soldered wires inside the loom (i.e. under the tape wrapping) were found to be twisted together  but not soldered. Imagine having to track that one down. it was described as manufactured by Honda but a repro and had Honda P/N

Just tring to modify an old pair of hair straighteners ( as you guess I have teenage daughters  ) to make a rig to fuse together plastic sleeving to get the original look on the connector sheaths. Anyone know where you can get transparent sleeving from of the original size?

Also worth remembering on looms where connectors are tinned that you can clean them up and then dip them in the dip type tinning solution used for PCB manufacture (Printed Circuit Boards) to replate. I did this on my 400/4 loom back in 1986!!

Thats a bit off. Especially being sold as genuine part.

I also recognise the "special tool" as I also have a teenage daughter. These things have to be pink now or they won't fit the bill 

Are you looking for the transparent sleeves that fit over the bullet connectors?

[Spitfire]

I cleaned up all the connectors on the F1, using WD40, and a very small wheel in my Dremel, then used dielectric grease on them. I bought some new connectors which look just like the originals from eBay, place called Yambits. But I have noticed since I bought them that their prices have steadily gone up, however they are a great match for the originals. Here's a good offer

Yes just the sleeve.

The Babyliss straighteners get far too hot and the other temperature controlled ones we have  are kn*ckered so I am going to adapt  the elements from the kn*ckered one onto a temperature controller and try that (I run a small electronics design and manufacture business so I have plenty of parts). will post my findings.

I am setting myself a weekly targets on the K0 and this week's target is to refurb the wiring loom without spending a hundred quid!!

Cheers Den- I Have found these from quite a few places but I want to recreate the hot fused sleeves used on early Hondas

[Seamus]

Would it be worth emailing these suppliers to see if they would just sell the sleeving?

I posted this on another site :


Back to the clear covers. Please don't mock the following 

Bought a child's skipping rope which had PVC outer tube for 2 GBP. had it analyzed as well as a '69 Honda terminal cover and basically the same PVC except that the skipping rope one had a child friendly plasticizer in it. But the OD and ID were too big. Heated it up whilst stretching it to achieve a narrower OD and the right wall thickness, then quenched in cold water. Cleaned the bore with isopropanol and dried. Then used my daughters old hair crimpers and managed to fuse the sleeving end to a piece of old Honda loom cable (the temperature needs to be just right to soften the PVC but not degrade it). I just need to make the right heated aluminium platens on my lathe to give the correct profile. then they will look just like Honda 'fused to the wire covers' (female bit of bullet). I will post full details and pics when I have finished it.

I was born in the early 50's you know and we had a 'make do and mend' philosophy drummed into us in the UK !!

Good bit of detective work there. I did wonder if RS would do some sort of electrical sleeving that would do.

Will there now be a run on certain skipping ropes ?

Recognise the sentiments of the fix it if possible approach. My philosophy exactly. My kids no longer throw broke things away without bringing them to me first.

[AshimotoK0]

Pics are coming - I am just perfecting the temperatures etc and I am now favouring hot air gun (controlled by a Variac to achieve optimum melt temperature) and then cold 'forming' platen tool I have made from two bits of aluminium. I even made some covers you can can 'prepare earlier (Blue Peter style!!) and then slip on the wire, using PVC bonding adhesive to attach to the wire. They are looking "Honda style' - well good enough for me anyway.

I am also  doing a  TOTAL refurb of the regulator, rectifier, start switch as well ( I have stripped these down to the component parts, replated and need to reassemble, I must be mad I know 

I have also used the tool I made to heat crimp the type of 'slip on' bullet covers you get off Ebay and they look pretty good and you don't need the skipping rope (apart from the ones which have 2,3 and 4 bullets going ito them)

For my bit on the starter solenoid see my comments inside this post, it will be updated once I have yellow chromate passivate plated the steel parts.

Ash,  You have too much time on your hands 

Cracking job though, glad to see that going to work has its advantages

  Sorry Seamus but you are a bit wrong there I work 6 days a week but there is nothing on TV, too cold to go in my garage to work on the K0 on an evening. My philosophy is that there are parts you can restore and parts you can't. I would rather save a hundred quid restoring my existing loom and spend it on bits you can't restore like worn out shocks and HM300's . Must admit I do geta bit obsessed though - its what I I call the 'K0 bug'.
