Stuck Clutch remedies

I didn't see a thread on this. What's worked for you in the past? So far I've read;

1) Get it rolling, pull in the clutch and jam on the rear brake. Okay, bit risky.
2) Add some Marvel Mystery Oil to the crankcase and wait I guess?
3) take it apart and clean, soak in oil, reassemble

I just put my CBX on the center stand and let it idle in first gear and apply the rear brake with my hand. Sometimes I have to bump it a couple of times but it always works and is safe to do. I would be careful using Marvel Mystery Oil as it contains alcohol and it is not good for seals and such. It is a great product but I don't think that is the place to use it.

How about you just take it apart? It just takes a few minutes.

There is another clutch thread here somewhere. from vandyke or something. Anyway, it is pretty easy to drain the oil, take the clutch side engine cover off and take the fiber and steel plates out of the clutch basket. Measure them, inspect them for glazing and warping. New plates and springs are always good. Install new gasket and there you go. Clutches are not that hard and need to be repaired occasionally.

If the clutch is just stuck from sitting it takes about 10 seconds to brake it free. It is a total no brainier to do. Any of the medthods mentioned will work. You didn't mention what motorcycle that you are working on. A stuck clutch on a CBX is very common after sitting just a short while.

Sorry, not a question of not liking the suggestions from another thread, to my mind if the next question is a new topic that doesn't have an existing thread, I should start a new thread, no? Talking about stuck clutches in a carb thread is going OT, no? I could list every question under my initial intro thread but, as a user and a searcher I like to see thread titles that match the content, and if the question has been asked before, I like to see people tack on the end of existing threads where possible.
So...I started a "stuck clutch" thread.
It seems unstucking a clutch is far more common and routine than I thought. I'm going to get all other systems operational first than I'll try to get it unstuck by the common method of running it and using the brake, whether on a stand or the street. If that fails, I'll tear it down.

Well, she did come out and sit on the Honda Sunday, just to see if she could touch the ground alright so she could ride it too. She can't.

I got it rolling down the driveway and with clutch lever in, jumped on the rear brake, did it three times, no joy. I guess I should tear it down or I could try going FASTER and doing it again. I was only going 5 mph or so. But it was the official first time it's rolled under it's own steam in quite a while.

The image of that bike rolling down the driveway reminds me of my first mini bike. I put it together with stuff that people gave me. It was direct belt drive with no clutch. I would push it down the driveway until the engine would catch and then ride around the neighborhood until I ran out of gas. Did I mention that it had no brakes and the only way to shut it off was to pull the plug wire. Laughing

Well I'm not quite in that bad a shape. I have brakes now! I regret putting fuel filters in though, they are a problem, they leak and two have broken. Now the lines are too short.....ugh. Oh well, no rush. Winter is sticking around for quite a while yet.
