You make a compelling point. I have had a quick trawl of the internet and find that the question of which oil to use is not one to be entered into lightly. I will still go ahead and change to 10w40 mineral oil. As you would say, “there is no try or not try; there is only do”

Now you tell me!!
However, I’m not just basing my optimism on chance but on the fact that after I soaked the plates, the clutch felt considerably better than before. Hopefully the change to mineral oil will also incrementally improve matters. I am looking for for all the small detail adjustments that will add up to a larger improvement, as I cannot see anything fundamentally wrong with the clutch.
Thanks for the advice.

Hi
I’ve checked the plates for flatness, all seemed ok. I am happy that the clutch lifting mechanism is working fine, the problem seems to be in the separation of the plates. Looking back I think that I can see what may have happened.
I believe that the F1 sat for many years after money had been spent on renewing numerous parts, I would imagine that the p.o. ran out of energy (or money). It was then traded in as an unfinished project to a local bike dealer in Norfolk who wanted to move it on quickly - this is where I came in as there is nothing I like more that an orphaned bike ( I have more in my shed)
I got it up and running but never touched the clutch. The bike had no oil in the tank when I got it and a stripped sump plug and I would imagine that the clutch was dried out. I assumed that new plates and springs would sort matters out, but thinking back, I don’t think that I soaked the new plates in oil and so just duplicated the problem. Things were definitely better after I soaked the clutch for a couple of days recently. Unfortunately I just changed the oil for fully synthetic, compounding the problem.
I will clean the plates and change the oil for mineral. Hopefully this will resolve the problem.
Thank you to everyone who contributed to the (hopeful) resolution of the problem.

Nurse Julie, I will give a mineral oil a try. I am supposing that back in the 70s, this is what Honda would have used? Any recommendations?
Thank you.

Hi Jedi
I adjusted the clutch as you suggested and went for an exploratory ride. The bike went into gear without a crunch but was wanting to be off by itself. It could be held on the brake. Within 2 yards the clutch was slipping so badly that no further progress was possible. Ignominious return to the garage! I reset the clutch, as per manual and tried again. The bike went into gear without a crunch, but again wanted to proceed with or without me. This time the clutch engaged and rode as I would expect it to. Gear changes were quiet, even into first gear, but I could not engage neutral when stationary. The bike would stall when held on the brake.
I think that it needs a good long ride with frequent use of clutch and gears.
Any thoughts anyone?
Thank you

Hi Phil
No, it’s just a smear of grease that I used to hold the gasket in place whilst I did a trial fitting of the clutch.
Thanks

A little progress! I soaked the clutch plates in oil for 48 hours, cleaned, adjusted and greased (where appropriate).
The bike will go into gear without a sound and will tick over, in gear, held on the front brake. So, not fixed yet.
I have attached a couple of photographs showing the clutch lift mechanism, clutch lever in and out.
I would appreciate any comment.
Thank you

What did the Japanese ever do for us?
I have taken a few photographs of the clutch lifting mechanism. Does it look as you would expect, or is it looking worn?
Thank you everyone for your insights.

Thanks Jedi. I will try this.. I think that the mechanism is working ok but it would be useful to compare the lift with a known working example. I hope that the force will be with me!

Hi Trigger. Firstly, thank you very much for the offer of looking at the bike. I live on the coast just east of Cromer, not far in a straight line from Horncastle but a little further when you factor in the Wash! However, my wife is having to shield at the moment and so visits are off limits for the foreseeable future. The summer may be a different matter if I cannot get this sorted.
When I fitted the new plates, I believe that I did soak them in oil. They have sat for about 9 months unused and so may have dried out in the bike? I’m going to remove the basket from the bike and check fit and movement of the plates in detail. I will re-soak and refit.
The Honda F/F1 parts book shows the option of either having plain plates or 5 plates and the composite plate. DS and CSMNL both show their replacement clutch packs for the F1 as having the ‘swirl’ pattern as opposed to the puck pattern. I don’t know if this is relevant to my problem
Looking at the line drawings in the parts book, the clutch shown appears to be the same as mine. What differences have you observed?
Lastly I greatly appreciate the help from the forum, the bike is too good to be abandoned!

Sorry Nurse Julie. Wrong photograph, it is shown on the fourth photograph.

Bryanj, thanks for the offer of the book. I have got the F1 supplement book. The line drawings do not really show any differences (that I can see).

Thanks for the advice. Nurse Julie, the big washer is shown in the second photograph that I posted. I left it on the shaft.
