140hp/11,800rpm 283kmh in 78 was not bad
The bike did not finish due to a trans/shaft braking and the project was
abandoned.  Here is Pie(t)ro Laverda starting it.

I've refrained from entangling yoose guys in hobot mechanical karma but
offer up this down and dirty ring OD size vs the bore intended for on
Nortons.
I had a LH jug smoking and gasket blow by both into cases and outside mess.
Turned out my pistons and bores are fine but the two top rings sent in new
piston set are unequal sizes and both gave twice too big a gap.  Solutions
is correct set of rings for .040" over bore. I clamp ring together with
small
vice grips as busted one skewing together by fingers.  hobot

  From Ken Canaga Left Coast Racing.

Just for fun, I went out in the shop and measured the closed ring
diameter for top rings from three NOS ring sets. I did them the same way
you described, holding the ends together with visegrips, and measuring
accross the diameter at 90 degrees to the gap. The +.040" Powermax
rings, still new in the Norton box, measure 2.903/2.904". The +.020" AE
Wellworthy rings measure 2.887/2.890". The Norton AE standard bore rings
measure 2.863/2.865". A single Hepolite Atlas +.040" ring measures
2.882". A set of used +.040" AE Powermax rings out of one of my old race
bikes measures 2.903/2.903". If your's measure 2.850", they are
certainly not correct, but it they measure 2.882" as you originally
said, they are probably normal +.040" rings. You need to be fairly
careful measuring with calipers. It's pretty easy to compress the rings
several thou by clamping them too tight with the calipers.

Other than broken ones, couldn't you just put the rings in the bores and measure the end gaps?   That would seem easier and more accurate than what you describe or putting them up against a brick wall then crashing into them with a battleship moving at a known velocity and timing the interval from when the ship first hits the side of the ring away from the wall till the time when the battleship then crushes the inside of the ring against its opposite side then adding for the two ring thicknesses.   The equation would be :  

Rate x Time = Distance  (plus, of course, what used to was the two ring wall thicknesses)

    Using a battleship minimizes the percentage overall system deceleration from accelerating the mass of the side of the ring away from the wall and any time spent in deforming the ring before the inside surfaces meet and stop the timed event if not the rest of the system.

Boy oh boy oh boy oh boy, Ken you know about Commandos and they sloppy
variation from factory and all that handled them later, so resisting ugh to slap ya
around,  there's a bit of a saga I've not dragged this list into.. But instead of throwing
my drink in your face I'll make ya read about it now...
Oil slot comma fatigue prone pistons were rubbing on smooshed down Al head
gasket the Combat piston move though so after 3 wks new timid riding one left
go, so had to have barrel scores re-honed but mechanic did the job and quit
before I got the pistons to him and left no final bore measures to go by.  I took
chance and stuck in the new .040 over piston/ring set w/o measuring ring gap.
Sealed up smokeless about same time full oil pressure hit 30-40 seconds. Stayed
good for few 1000 miles then RH smoked. Discovered a carb boot gap let in
grit, fixed that and RH stopped smoking after a while. A few hundred miles
fine I had short notice 500 mile Texas trip I didn't final re-torque head prior
and LH smoke began to show up on return leg.. Cleared up in minutes at
hwy speed but last 1000 miles over fall smoked so much it misfired some.
If also was blowing oil out LH copper gasket.  Opened up to find only thing
wrong was .025" gaps. Manual says .010 1st and .008" 2nd ring gap.
But because of the unknown bore to start with I ass-umped the bores were
too big after the re-hone.   Finally though to compress a ring to find one
on the small side for 40 over rings and the smoker side normal for only
 a 20 over bore.   The ring set sent in the box are the wrong mixed sizes
but fooled me a while as worked a treat for a while.  Blow by apparently
did in the gasket sealing, especially on missing a vital nip up session.
So my lesion is never skip and double check step like opening up a
fine runing motor, with hidden time bomb or ass-ump repected suppler
checks everything to Nth degree.  Turns out Trixie Combat bores are
.005" under size of a  full 2.915" 40 over bore and piston clearance
is only .004" both by calculation and by direct measure. So a proper
off the shelf 40 ring set should need a bit of file to perfect gaps.
Manual says make 2nd ring 20% smaller than 1st ring but I've read
hot rodders find 2nd ring gap 20-25% bigger vent pressure between
rings for better top sealing.. Any thoughts on that in a plain jane Norton?

Some plug caps come with a screw type "connector" to attach it to the wire.  Does someone sell a double end screw type connector?

I did this once by stripping the ends of the plug wire and soldering them together.  I then used some of that liquid insulation painted on, in many layers, with a brush until the gap was filled.  I then used a piece of heat-shrink tubing to seal everything.

Its a Spandon Aprilla V4 with Norton inovation of adjustable engine and

 If the wire comes out of a bump on the coil, you can just cut away the top and it should come out.  Add the new wire and JB weld the top back on. The easiest way, is cut off the wire close to the coil, stick in a bit of wire (about the wire size of a paperclip) into both ends and heat shrink tubing over it. Maybe a couple of layers...
