Now we might be getting somewhere. Does anyone have a photograph of a F1 clutch? How does it differ from my clutch?
Thank you

I would be more than happy if anyone can spot some obvious fault, I’m running out of ideas.
Thank you.

Hi
As promised, some photographs of the clutch assembly.

Hi
No, the bike does not have the double plate. I’ll post some photographs tomorrow after I’ve pulled the clutch out.
Thanks to all.

Thank you for all responses. I believe that the plates are correctly located in the basket as they fit well down into the clutch basket. I will check again when I dismantle the clutch (too dark and cold at the moment!)
I have cross referenced the parts with an F1 parts book, all parts present and correct but, again I will check after dismantling.
If I give the adjustment screw an extra half turn clockwise, it slightly improves the situation but the bike is still not rideable.
I’m certain that I am missing something but cannot, for the life of me, think what it can be! I can see the bike being consigned back to the shed!

Hi
Thanks for replying. Yes, I do not think that adjustment is the problem. When adjusted by the book(clymer) screwed in until it touches and backed off quarter to half turn, the angle of the arm is approx 7 o’clock. The clutch action (from the clutch lever) is smooth. The clutch lifter slides in and out smoothly when the lever (handlebar) is operated.
I have just taken off the outer cover and the clutch lifter plate. The clutch plates all look correctly located within the basket. I will remove the clutch plates when I return from walking the dog. I have done this procedure at least half a dozen times over the past two years and it is doing my head in!
Any suggestions very welcome.

Thanks for the response. Yes, I fitted the clutch in same order, bevels the same way. The symptoms were the same with the clutch when I bought the bike, as when I replaced the clutch with the new one. I also replaced the springs.

Thanks for the prompt replies but I must not have expressed myself accurately enough. I did adjust the clutch as per the manual, turn clockwise until it touches and then back off. At that setting, it will not allow me to select a gear without more crunching than my mechanical sympathy would take and then the bike will take off or will stall if I use the brake! I turned the adjuster screw half a turn extra clockwise to see if this would allow me to select a gear without the above happening. It almost feels as though there are too many clutch plates!
When I had the clutch apart I ‘dressed’ the slots in the clutch basket to reduce friction and I have changed from semi-synthetic oil to GTX to see if that had an effect.

I took a punt on a non-running 1976 F1 for not a lot of money. I worked through the bike and now it runs, stops and generally does everything reasonably expected of it except for the clutch. When I bought it, I assumed that the plates were stuck and that a good ride would clear things and when there was no change I removed the clutch and checked and cleaned everything. There was no change. The bike would only go into gear with a nasty clunk and the bike had to be held on the brakes, eventually stalling. At this point, I put it away and concentrated on the bikes that were behaving themselves! When the pain had subsided, I bought a new set of plates from D Siver and fitted them; again no change. The bike was banished again. Recently I had time to look at it again. Everything seems to be correct. The clutch action is smooth and the cable is adjusted as per the manual but it still will not go into gear without a clunk and it drags badly. I have tried screwing in the clutch release by half a turn but it still clunks but not as badly. Can I turn the clutch release in further? ( I don’t really like to do this as I feel that it should work as per the book). Any suggestions would be gratefully received, as I have now had the bike for two years and I would like to ride it when the world returns to normality.
Thank you

Hi
Would be interested in the rear chaincase if you have it.

Hi
I have a 1961 Honda C72 and am missing the chain guard. Do you have one and if so is it the same as one fitted to the C72?
Regards
