Good progress though Johnny and working on it is obviously now getting under your skin👍.
Amazing to think you can still get piston rings for something nearly 100 years old and considering Jag owners struggle to find replacement parts for cars 10 years old!

Very sad news Ted.
I think the previous replies by others sums it all up, we never know what life has in store for every one of us on a day by day basis. Personally I have always believed in fate and how everything happens for a reason both good and bad. There's the old saying that you have to endure the rainy days to fully appreciate the sunny ones.
I hope you both take the positives from the situation, Morgan beat the odds he was given at birth and went on to live a much longer life than predicted with the help and love of those around him.
Best wishes to you both.
Dave

Good luck with the op Dennis. I had a biopsy carried out on my right ear a couple of weeks ago and it is still too painful to even attempt to put a crash helmet on! Carpel tunnel issues, you must have been a MGP or Superbike racer, a true motorcycling god

That was a good workaround Ian. The lathe is the best tool I have ever bought, so useful. I used it this week to enlarge a centre hole in a 20mm stainless washer by 3mm. Turning it up in the lathe ensured it was circular and it fitted perfectly.

The USA is now experiencing national grid problems with demand outstripping supply. The generating companies are saying it is caused by the increasing amount of domestic heat pumps and the increasing number of electric vehicles requiring regular charging! When all our politicians decreed the world go all electric where did they think the increased energy requirements was going to come from!
It's alright for the climate activists to say wind and solar but you can't produce solar power when the sun doesn't shine (common in England especially in autumn, winter and spring, and turbines only work when the wind blows! Solar panels only last 20 years and have high replacement costs. As for building vast wind farms out at sea, they are built by American companies because they receive massive subsidies from the UK government to build them, another type of lend/lease where the tax payer is ripped off. Off shore wind farms are also a big danger to sea birds with a massive increase in death rates.

I have just read this interesting piece on the Mike Nixon Motorcycle Project page: 'The correct procedure is to remove the bolt serving as a sealing plug on the plunger. Then put the crankshaft at TDCC (compression) on the #4 cylinder. Insert a Phillips screwdriver into the hole the plunger resides in and while pushing with moderate pressure, loosen the tensioner locknut and lockbolt, rotate the crankshaft 10 to 15 degrees, and snug the lockbolt and locknut. Release pressure on the plunger and replace its sealing bolt. This is the correct way for the CB350F, CB400F and CB/CL360. Don't use any method that includes running the engine.' The above was the method I was told to use back in the 1980’s to adjust the tensioner but only if after adjusting the tensioner in the ‘normal’ way as described in the Haynes manual with the engine idling at a steady 1200RPM there was no difference in the sound of the engine indicating the tensioner arm was sticking (a sure sign of damage to the pivot point caused by a slack cam chain eating into it and also potentially into the top crankcase  ). So the question is who is right and what methods are used by the 400/4 collective on the forum?

Ken (formally Oddjob on here) made a few sets. I purchased a set and they are very good quality. He was going to put a few sets on ebay so that would be your first port of call. Failing that Mike Nixon in the US can supply them but they are expensive. His website is here: https://www.motorcycleproject.com

Or maybe a couple of turns of the white PTFE tape on the thread (just make sure it is only on the thread and not protruding on the end in case it blocks the oilway to the switch).

Are there any engineering shops close to you Roo that could ream them for you? I'll be taking a trip to the engineering shop I use soon and I could ask them if you like (cheap postage for four tiny jets!). Although £39 for the set of reamers is probably cheaper than taking them to an engineering shop (and you get another tool for the toolbox!).

Standard stainless not a good idea in high stress positions
Good point Bryan. I'll get some Honda items from HGB. I'll frame the two stainless ones considering they were so expensive.

Welcome back to the forum Tim. Post a photo of the bike when you can.
As the other Tim said, you really need a 400/4 and preferably in yellow (Tim will explain why😉). 😁😁😁

Excellent progress.
I sympathise with you about all the last minute hold ups though. I went to fit the rear shocks on my 400/4 yesterday in readiness to lift the frame over the completed engine only to find the 10mm threads in the lower shock mounts are 1.25 pitch and normal 10mm 1.5 pitch thread are obviously too big! Trying to find stainless 10mm bolts with 1.25 pitch was a pia. I found some in the end but they were £7.28 EACH! And I thought Honda bolts were expensive!
Good luck with the rear wheel, once in at least you will be able to move it around👍.

Alex, try this guy, he is normally at the Kempton Bike Autojumble and is the SE Supplier of TEC shocks. He had a few pairs left when I last saw him before Christmas.

Try Terry at Stotfold Engineering, he's near Biggleswade. I took my Triton front wheel to him because it was grabbing. Turned out the drum was slightly oval due to being pulled out of shape by the fitting of stainless spokes. He has a lathe big enough to get a whole wheel in complete with tire. He also machined the brake shoes to match the drum. http://www.stotfoldengineers.co.uk/motorcycle-restoration/
