Sticky Clutch ?

bonjour · Post by **bonjour** » Wed Dec 08, 2010 11:51 am

Hi all,

Im almost done restoring my CB77 , and was busy with the clutch and cable.

While testing, I found that the clutch does not disengage , looks sticky from what I think.

But, is this 'normal' or 'common' for these old CB's that the clutch is kinda stuck when they have been sitting for a few month's ?

I know it's a pretty common problem for 70's or 80's CB's , but is it also common for the 60's bikes ?

I could not get it loose (rocking the bike a bit while holding the lever)

The engine has not started yet.

Anyway, is this a 'common' problem for the engine after sitting ?

Thank you :)

Yes, fairly common! I have been able to unstick them by riding the bike a bit, and pulling and releasing the clutch lever while riding. You need to push off, or start on a downhill to take off with no clutch. Don't try this in traffic!

Thanks, I know enough now :)

I have experience with this, so I know how to handle it.

I just wanted to make sure.

Best thing to prevent it from what I know is to start it and use the clutch once a week, lol :D

Thanks for the quick response, I need to update my project topic again, sorry for that.

Hi,

I would consider taking off the clutch cover, remove debris, disassemble the clutch and check all parts. It's a little hard to understand why you wrote this and act not accordingly.

It's just there to keep big flying parts out.

Mostly the clutch plates make a mess, big chunks of 'rubber' can fly of and also tiny bits of metal.

If these bit's get sucked up by the (already) delicate oil pump, then the pump does not last long.

Just keep it there, you really need it.

The clutch plates generally create the most mess in any engine

Hi,

Not in any way take it offensive , just an observation.
Is "the engineer in me" a good or a bad thing Ed ?
or is it good as long it stays inside ?
