So you'd like to beat it to death some more? :)

The need for a constant supply of lubricant to the pivot is unnecessary in my opinion.

Hi L.A.B.
Not really. I get wrapped around the axle on things and am looking for a direction that works.
I kinda like the idea of using crank case vapors plumbed to the swing arm as the constant supply
Thank you

Install new sintered bronze bushings AFTER soaking them overnight in 140w oil.

Fill the spindle cavity from the top bolt, and forget it.

Adjustable Ikon shocks are hard to beat for the money along with adjustable compression/rebound inserts for the forks.

As far as the swingarm spindle and bushes, it seems a lot of people simply jam the thing together (Maybe even sand paper the bush ID) then in some cases force the swingarm over the cradle then wonder why the thrust faces of the bushes show wear or galling.

With modification you can add PTFE thrust washers along with a few other things. (Including machining a facing mandrel that uses the cradle spindle bore with the stock thrust set up)

Maybe GP is thinking of YSS shocks.
 
Like a drunken politician my spending frenzy continues.....
The OE rims that came with the bike are non-serviceable. A pair of aluminum rims with stainless steel spokes & nipples were included in the purchase. They'er marked; ENINCO 11.99 on one and VALANTE 19x1.85 S40 on the other. Good, bad or ugly? I don't know enough to make an informed decision.
The condition of a 47 y/o British motorcycle electrical harness is best left to ones imagination. Not being authenticity obsessed, my preference is reliability and simplicity. Again I request suggestions!
The responses I have received from Access Norton forum have been great and have kept me from making unwise decisions. All replies are greatly appreciated!

You spiked my curiosity and before I get too far along in reassembly, could you tell me more about the;

Norton fitted one harness to all bikes, leaving wires unconnected that weren’t needed. Even polices bikes I believe. Bottom line, with the best will in the world you’ll not get the simplest or nearest solution using a stock harness.

When I rebuilt mine i kinda concluded that I was changing so much, there was no real point in even using the stock harness as a starting point.

Making your one harness is surprisingly doable. And you can use better materials, route things exactly how you want them, etc.

However, the latest manufactured harnesses don't appear to have the Interpol and other unused wires. Not that having a few unused wires makes any difference as far as fitting a harness is concerned.

Eninco is Brazilian, apparently. I've never heard of them (11.99 could be a date code?).
How about some details?

Diameter? (19"?)
Width? (internal)
Have the nipple holes been punched (or drilled) already?
If so, are there 40 nipple holes (or 40 dimples if not)?
New or used? If used that might suggest it could be from a totally different bike in which case it is unlikely to be suitable.

I can find no information about Valante.
19 x 1.85 (WM2) should make it the same size as the original rims.
Same new or used and nipple hole questions apply.

Note that the front and rear rim nipple holes should be punched/drilled differently as the front and rear hub diameters and offsets are not the same.
The front rim is 'handed' due to the extreme hub/rim offset, therefore, if the nipple holes are angled correctly on both, then one rim is front only (disc hub) and the other is specifically for the rear (drum hub).

Excuse me........after a closer look both rims are new and stamped with; 19 x 1.85, Valante and Eninco. 40(ea) drilled nipple holes on both rims. I believe 11.99 would be the date of manufacture.
With a sharpie someone wrote; "front Norton disc, the other marked Norton dear drum brake.

I'm wary about lacing them up and finding problems midway. With that said, I'm looking for a set of rims.

Perhaps if you could post a photo or two, we could be more helpful.
 
Tap them with a screwdriver tip, all the way around. If you get a nice metallic "tink" every time, I'll bet they're sound.

If you see obvious corrosion pitting going deeper than your pinky fingernail thickness, they could be shot.
 
Thanks,
The original rims that came with the bike are severally corroded. In my day of riding, Akront & Borrani were the names I was familiar with. I've been out of the motorcycle loop for decades and don't know sheet. The aluminum rims I have àre from "who knows where" and I hate throwing good money at bad. That's my concern. I like to do things once.

There is nothing wrong with those rims (If they are drilled correctly especially the front)
If you have spokes just loose lace them to see.

The rims are drilled correctly. With "handedness" of the new rim determined the original cancer stricken wheel has been disassembled for lace up.
Aware that 4(ea) types of spokes exists, the four consecutive spokes just prior to the valve stem were labeled and retained for reassembly/comparison purposes (which type spoke came from where). I have 40 new stainless spokes & nipples presumably from Andover. 30 of these match up rather nicely to what came off the rim. They also match up to what Andover lists as replacements and I would have no problem giving them a go.
So far so good ...........except nothing that resembles this spoke with this bend radius came off the rim;
https://andover-norton.co.uk/en/shop-details/16176/spokes-per-10-9-gauge. The 10 removed from the rim had a much tighter bend radius
and I'm lost with how to proceed. Thank you
