That these clutched tend to stick, I just accept it.
I don't know any better then that they stick when they have been sitting, it surely isn't because of thick oil. Because the oil in it ain't thick.
I don't see it as a problem, but as some character. In the moped world, ALL CB's have sticking clutches when sitting for a week or 2 orso.
I personally THINK it's a combination of strong clutch springs (which press the plates together) , material of plates, and a clutch that run's out of oil (drips off ofcourse)
Because when you start the engine once a week, use the clutch 3 times, you have no stickin' clutch.
It really happens when they have been 'sitting' just like I stated.
Why does it stick only after a week ? Why not after one day or 1 hour ?
I can't think of any other reasons, or a way to prevent it, it's probably a combination of all 3.
As for your experience on this, how do you treat you bikes when you don't ride them for a (longer) period of time ?
Crank it ? Start it ? Drive a circle around your house once a week ?
If you really don't know these problems and you REALLY let your bikes SIT for longer periods of time,
then hell... you got yourself lucky I guess. Because these problems are fairly common up to 1980's.
Or you must be doing at least something different on your clutch.

At times ya imply that ya are the one with the answers then follow up with the statement below.
To many times back to the OIL thing! MAYBE!
Don't ya see that during the clutch discussion(s) that this area of these HONDAS has things happen and (recall all the different design changes) they are common with other owners.
Thick oil, new/old parts, misadjustment.
Once again the engineer statement?. ......lm

No, not yet, maybe after the winter ?, I'll see.
No assumptions, just experience on my two riders.
I look for reasons, that's why I use the magic word maybe, as I'm not sure.
To make this conversation going somewhere, does anybody know why the clutch sticks after a few months of sitting ? is it the friction material ? the construction of the clutch ?. oil ? other reasons ? a combination of the above ?
Both my riders have a lot of nos clutch parts in it, is it something that only seems to appear on used clutches ?

sticky clutch
I have no answers or theories about the why or wherefores of sticking clutches.
The clutch plates in my Dream was cleaned and installed 6 years ago and it has never stuck.

I have to concur with Mike. I disassembled my CL's clutch and made sure everything was right and flat. This has been two years and it hasn't stuck yet! It often sits for over a month. By the way, I use Ed's recommended "THICK" oil and change it regularly....................................D

Hi,
I wasn't implying that I had answers to this particular issue, if I had answers other than maybe this or maybe that, I would share that with the forum.
I did however changed the clutch of my CB's for different reasons (neutral issue).
And yes, the engineer in me wants to have some decent explanations or answers to the theory's here, that's my character.
In winter I let the bikes sit for two or three, sometimes four months, depending on the salt on the roads, so there is time enough to get stuck.
So -1 for the thick oil theory, thanks.

I have the same experience here, rebuild, rode it, and never ever a stuck clutch. Both bikes were not running when I got them, and I never tried to run them, as I directly started to restore.The clutch plates in my Dream was cleaned and installed 6 years ago and it has never stuck.

Sticking clutch plates is a consistant subject on just about every motorcycle forum I've been on.
The one constant seems to be "time", and the longer they sit unused, the more likely to stick.
While working at a dealership, I can say that bikes that didn't sell quickly and sat unstarted for months (or years) tended to have stuck clutches. A simple rocking back and forth would usually break them loose, and we never had to disassemble one to free it.
Or, when first started and dropped in gear they would lunge forward and die, or break loose, only to be fine afterwards.
I don't think oil weight or type has anything significant to do with it.
Most new bikes came with 10-30, and some even with full synthetic.
I think there are 2 different sticky clutch mechanisms....short term and long term.
Short term caused by surface tension or capillary action of the oil migrating away from the plates causing a vacuum between the plates, or
Long term caused by the oil reverting back to a more basic state...asphalt or tar.
And, it all may depend on what your definition of the word "stuck" is.
Short term stuck......have to rock the bike or otherwise break it loose.....or
Long term stuck.......take it apart and pry them loose stuck.
I've experienced "short term stuck" on every bike I've owned.
I've experienced "long term stuck" on several (but not all) old bikes that had been sitting for years.
....my .02, which I will assume as fact until otherwise convinced
