Air in Clutch line

[DallasTx5249]

Hello,
I have a '97 Tourer that I trailered to the Honda dealership 2 weeks ago to get the clutch working.  they bled the clutch line and it worked normal/great riding home.
It sat for 2 weeks and now does the same thing.  Unable to shift into gear when the bike is running.
This problem just started with no warning.
There are no drip marks under the bike, none, zero,zip.

I do have a service manual and feel capable of repairing if it is not something major.
Any help whatsoever, ideas will be greatly appreciated.
Thanks from Dallas Texas.

Almost any shop manual will describe it in detail. I have seen this problem also be the clutch plate rivets coming loose....air is better.

Dallas: I faced this problem with my Shadow. Somehow the air did find the way into clutch line although there was no drip marks under the bike. I was in your shoes having no idea how to fix this issue when there was no leak anywhere in clutch line. I swaped all rubber caps both in master and slave cylinders but it didn't help until I swaped the whole master cylinder. It resolved my problem although there was no leak at all!

Just my 2 cents... So be aware that it might be not so easy to find the real reason of this issue.

Hey Sergey,
Thanks for the info,  I will have it looked at ASAP

I couldn't get my V45 clutch to disengage.  It started with it re-engaging while I held the clutch lever in.   Eventually, it got to the point I couldn't disengage the tranny.  The bike was about 12 years old at the time.

I figured it was a leaky master or slave.  So, rebuilt both of them to no avail.  Let the bike sit for 7 years until someone mentioned that perhaps the hoses had softened a little bit and were expanding with the pressure.  Wouldn't take very much give before the clutch wouldn't actuate.

Replace the rubber hoses, bled the system (that was painful with a completely dry system), and presto....been working great for the last 5 years.

Just kind of an off the wall cure that had never crossed my mind.

Good luck,
Chris

The clutch system can be bled just like any brake system. There is a small bleeder valve behind the carbs, for bleeding the clutch system.
If you are having trouble, I would thoroughly bleed the system, and watch it closely, hope that it isn't your master cylinder, they can be pricey.

Had a similar problem wiht my old Interceptor after rebuilding the slave cylinder. Tried the old conventional way of bleeding and just could not get any pressure build up in the system. Have had some Euro cars with hydraulic clutches that required "pressure bleeding".....either forcefully pushing or pulling the fluid thru the system. So I took a 30cc syringe and hooked it to the bleeder and pulled the fluid thru. Has worked fine ever since. Commercially there is somethig called the Mighty-Vac, I think, that does basically the same thing.

they have whats called the Mixmizer which I used to change my clutch fluid. The best part is it only costs about $4.00 and works like a champ. You will have to get a piece of tubing to connect to the valve. I used one that came with a battery and it fits tight.

That reminds me that I have to find the bleeder for the clutch on my GL1800. I am replacing all the brake fluid on it. But haven't done the clutch yet.
