I acknowledge that I & many others are basically trying to make a silk purse out of a pig's ear. We are endeavouring to make an Italian shopping machine decades old into something re-engineered, whereas it should have been scrapped long ago.
You are obviously a hands on guy. Unless you can somehow source a NOS genuine OEM loom, your best options are to either purchase from the likes of Anthony Tambs, or build your own using the original as a pattern. That way, you can select the best cable, connections/terminals & sleeving. Somebody will hopefully kindly correct me if I am wrong, but tinned electrical wire may be the best to use.
As for ignition, I am extremely outspoken on the subject, but I think that most people change to electronic for 'reliability'. Just browsing this Forum will indicate otherwise & all I can suggest is to get a well set up contact breaker ignition with 12 volt DC to a battery so that you can be seen in the event of stalling or a breakdown.

rossclark wrote:To answer one of your original points - the standard loom can still be used with an electronics setup. In either AC or Dc format it's a matter of getting power from either the rectifier/battery combination or regulator into the loom - this depends on the type of junction box you use.
In the original Dc configure with the square plastic cased rectifier the junctions are all built into the top of the box. You'll discard this along with the coil. So you you need to find a new junction that does what you want. These are usually the round type from the DC SIL GP - all the connections are cross connected in this type except the greens.
If you go to electronic there's three wires from the stator go to the CDI - usually red/green/white and you take the green from the loom to the other terminal on the CDI.
There'll usually be one or two yellows from the stator - depending on if it's been wired for DC (2) or AC (1). These connect to your regulator / rectifier.
For the simple AC Vethpa type regulator the output simply plugs into the junction box providing power to your brown/purple/pink in the loom.
For DC you connect the output of the rectifier to the battery to charge it and also to the junction box providing power to the loom.
The main difference between an AC and DC loom is the spur for the battery.

"if I stick to a standard loom (with battery) for the time being for points/coil etc and at a later date possibly go electronic ignition (only a thought at the mow) is it easy enough to add electronic ignition with a standard loom (ie plug and play) or would I need to replace the whole loom again?"
Again. A standard loom should be fine. (However it is acquired).

If you need a new loom & want to buy one rather than re-engineer/replicate your own, it pays to buy a good one. Especially if a fellow Club member makes them. If you do go that route, ask about tinned copper wire. Perhaps that is over the top, but somebody on this Forum has even spoken of it, so I feel sure I'm not alone in believing it to be beneficial. Or I could just be mad

Admittedly, the new looms that I have acquired have coped as far as ratings, but there has always been quality issues compared with OEM. Silly things such as terminations coming off, sleeves of the wrong sizes &/or splitting.
That's why I will either make my own in future or buy from somewhere within the UK where they are physically made. Preferably within kicking distance....

I understood that Paul
Often it is assumed that the old OEM's are beyond their 'Use by date' but I remain amazed how well they were made as far as mechanical properties. Thankfully, I have kept all old looms & portions of them, along with stators, as in general, if it was required to replicate as closely as possible, only the terminations may require attention & the sleeving, which we all know, does a brilliant impression of uncooked pasta in terms of brittleness.....
