It's looking nice apart from the lack of mudguards, any in the pipeline. To me bikes always look like they are not finished without them.

@lchris21 Just noticed that inspection lamp in your pic. I have its twin - bloody nuisance of a thing. It's forever shining in your eyes despite the shade/deflector, and I'm not going to tell how many times over the early years of my working on & under cars I've driven off for a test drive with it still hooked underneath/on the car.....

Yeah,
Used to eat old tungsten filament lamps when It was dropped. Got a compact fluorescent in there now which helps.

You could buy 'rough service' bulbs, but even the highest wattage ones were dimmer than ordinary ones. They did resist knocks better though.
My local ironmongery might have a few still tucked away somewhere in the back shop (never to be sold now....

I'm sure rough service lamps weren't banned, I have certainly had some from an local electrical wholsaler just before the lockdown. I supply them into a furniture factory, 50 at a time.
They aren't old stock, they ordered them in for me.

where was I..............
Waiting for bits mostly, what with other pressing engagements, everything in the supply chain is slowed right down
...........back to clean up, and top end rebuild.
Clean up first, the pistons were treated to an ultrasonic clean. Tip I read was to put them in a bag then use the cleaning chemicals in the bag at a higher concentration to enhance the process, worked a treat.
Checked the head out for warpage. Came in at 0.003" which was well within the manual specs of 0.010" so set at trying to get it better with some 650-grit on a flat surface. this was turning into a right ball ache so as I was leaning on the milling machine at the time I decided to put it too good use
. Only had a small fly cutter so made one of my boring bars fit and used a CBN tip to get the head as flat as a flat thing.
Also had to order some new inlet valves as the stem heads were looking a bit too worn. Lapped them in with the old cleaned up exhaust valves.
Polished up the cam rockers and got rid of all the grime and paint.

Got some new paint on the head and barrels and set about baking them as per the paint manufacturers instructions.............90deg for the head, 200deg for the barrels........
Whilst I was baking the barrels I heard a noise coming from the oven..........both sleeves had decided to make a break for it 
.................quite comical really, after the initial horror as Id only a few days earlier watched Allen Millyards video on how he gets them in an out of the barrels on his multi cylinder engines.
Left them all cool down, cleaned up the bits and bobs, reheated then refitted them.....3 times.......had to make a clamping jig up in the end to hold them in place while they cooled to prevent the liners creeping. All good and flat again.
Cracked on with the new rings, and checked them against the old ones, and the bores. The old ones were on the limit and the new ones confirmed this.

Whilst the head was off, i took the opportunity to get rid of the original rocker shaft covers. They'd seen some screwdriver action over the years and were looking pretty shabby, so I turned up some new ones and broached a hex in the end using an off cut allen key.
Turned my attention to the front cam chain guide which I found lying in the crankcase when I took the head off. Common fault with these apparently? The bonding deteriorates over the years and the wear strip just falls off and sits there, sometimes it falls to pieces and ends up in the oil pump screen, other times its just sits there leaning against the chain. Luckily mine just sat there, and I manged to find all the parts in the crankcase. Ordering a replacement was an option but most suppliers have online virtual queues so as Ive had enough of queuing for groceries lately I ordered a piece of appropriate material (Nylon66+Moly) and made my own. Bonded it in place with some JB weld and belt and braces it with some recessed aluminium rivets...............if it lasts 44 years like the last one, I'll be in my 90's and not that bothered about it next time it fails

You obviously read backwards perfectly
