Jubilee do I have the correct shocks.

Do I have the correct shock shocks.
The bush in the top of the shock absorber in the frame opening is as wide as the opening, the metal bit holding the bush is not as wide as the opening, is this correct. Don,t want the shock sliding on the bush.
Starter pawls
Forums
Hi all, I've sorted the electronic ignition and timing on my Electra now moving on to the starter. I have all the parts I need except the 3 sprocket pawls, pivot and engagement pins, the sprocket shaft washer that sits behind the circlip, the 3 studs that hold the outrigger plate to the engine case and the starter chain tensioner. Does anyone know the diameter and length of the two types of pin, the size and thickness of the washer and the thread on the 3 outrigger studs ( think the nut end is 5/16 BSCY but other end may be different).
Navigator Frame Painting
Forums
Hi all,
At long last I found the time to drop off my Navigator frame to have it straightened by Abba Engineering in South Woodham Ferrers yesterday and will report back once they have finished the work. They come highly recommended and certainly seem to know what they are talking about so fingers crossed!
Washer on big-end nuts?
Forums
Hi there. Still gathering bits for my ES400 as and when funds permit, so the new b/e shells, nuts & bolts arrived today. Looking again at the lightweight engine exploded diagram in the manual, I saw it shows washers under the b/e nuts. So I looked at the Andover Norton images for the Commando- no washers. Looked on Fair Spares, they show washers for L/W and early dommies, no washers for late dommies/ commandos ie 1 1/2" crank yes, 1 3/4" crank no.
I'm sure in my days past of various dommie engine rebuilds I only ever used the self-locking nuts.
Jubilee Wiring Diagram
Forums
I have a Jubilee Deluxe with a dubious past, it has been upgraded at some point to 12 neg earth, and has a Pazon Ignition unit, as far as I can tell its never been run ,it was all held together with tape ,twisted wires and cable ties using fuses, rectifiers and capacitors that should have stayed in the scrapyard, basically in an awful condition. So my intention is to replace the whole wiring loom.
My question is, has a wiring diagram been published or available , I cant locate a decent one online.
Any advice most welcome.
Thanks Andy
Wet plugs Jublee
Forums
Earlier this year I started my Jubilee for the first time in many years. It now starts first or second kick. The problem I have is that if I switch off the ignition and then try and restart the engine soon after it refuses to start. The cause is wet (champion) plugs. Once I dry the plugs it will start.
What will cause wet plugs after I switch off the ignition. Both cylinders run normal and get up to temperature. I cant leaving it running long as its in the shed, I value my old lungs.
At the moment I cant get it out of the shed until I sort out the front wheels and forks.

Lightweight Gear Lever
Forums
I see there’s a couple of comments in “parts commissioning” forum (sorry but don’t seem to be able comment there) for lightweight gear levers. If it helps, I bought mine from “Classic Bike Shop” via eBay @ £25.95 in May this year (listed under 04-0632, 04-1311, 06-1499 Norton & Amc Gear Lever), seems to fit perfectly, 5 inches long and sufficient offset to clear the gearbox casing.

Jubilee valve seat cutter size
Forums
I have replaced the valve guides in the cylinder heads of my Jubilee and I have purchased new valves and springs. Annoyingly, one valve seat needs to be re-cut. The valve guide is correctly installed so it must have been a previous problem. The valve stem is about 7mm (9/32"?) and I can't see a suitable valve seat cutter for sale, only 3/8 and 5/i6 inch.
Does anyone know the correct diameter for the cutter stem and what the valve seat angle should be?
