Okay so the bike sat for about six months. When I went to start the bike it was missing on three cylinders. so I pulled the carbs and clean all the trash out of the carbs, replaced the o rings on the fuel rails, and replace all needles. Install a new set of plugs and it runs like its new. So I put the tank back on tonight and went to take her out for a ride. I got on the bike it started great tried to pull in the clutch and the lever did not move much, maybe 1/2 inch. I placed the bike in 1st gear and let out the clutch and no forward movement. The engine didn't slow down R.P.M.s steady. Just sitting there clutch released in gear and no movement. So I pulled in the clutch and shifted to 2nd gear and released the clutch and no movement. Its like the rear tire was in the air. I do hear noise (sounds like a dry bearing) coming from the clutch area. I had a new clutch master cylinder so I installed the new one and bled the system. Same results. still can't get the clutch to engage.
Bike has 235K miles on it. I replace all the clutch about about 35K miles ago.

It ran fine when I parked it!
Since I last road the bike....About six months ago.
I replace the rear tire... I've done this many times and never had a problem.
I will start investigating in the morning. Guess I'll start at the slave cylinder and see if its stuck in the extend position.
Any one else ever had this happen?

I don't see how the slave could be stuck if it bled correctly.
Sounds like pinion cup symptoms.

I don't see how the pinion cup can cause the clutch lever to have reduced travel. Whenever I heard reports of reduced clutch lever travel it turned out to be the pressure plate separating. Since the clutch is newish, could there be a rivet or something left over from the old one that is now stuck in the clutch plates? |

I don't see where it says you bled the clutch? Have you done that? Just curious what the outcome would be?

I'm going out to the garage in a few to recheck my work. I keep coming back to is it was fine when I parked it, so it must be something I did while replacing the rear wheel. i always take my time and and inspect ever thing for wear when working on the bike.
i'll figure it out today.

Sounds like classic rivets from the pressure plates in the clutch.
If it works one time, and then happens again (back and forth), then there is something between the plates making it act like the liver is pulled in.

I focused on the non movement when in gear and the clutch lever out. Can't remember hearing about that symptom being clutch caused, even with a trashed rivet plate. When my rivets went away, the clutch still operated and the bike moved. |

Don said he bled the system after installing a new master cylinder. I too am curious of the cause. |

It was the slave cylinder.
When I went to loosen the three bolts to remove the slave cylinder it had spring pressure on it till it was about 1/4 " out,
I removed the cylinder but could not get it apart. I even tried 120 psi of air pressure. The way we did it at Firestone back in the day.
So I reinstalled it and bleed the slave cylinder.
I used master cylinder to try to push the piston out of the slave cylinder.
It worked but it took a lot of force with the clutch handle,
You could feel it jumping and binding all the way out.
Then I pulled the slave back out again and the piston was still stuck with the seal half out.
It piston came out with a little air pressure.
All I can figure out was the slave cylinder had built up so much crud that when I bleed the clutch I forced the piston forward into the crud and bound the piston to the cylinder.

That's a new one  Do you feel the slave will still work correctly? No plan to replace? |

I'm checking prices on a new slave cylinder now.
I've got the old cylinder soaking in some purple power to see if it will clean up.

Because it was stuck, bleeding made no difference. I've never had to work on a slave. I see now, it doesn't seem to matter if the slave is working or not, the system will still bleed. The manual states to check for scoring or damage on the slave, weakness or damage on the spring and wear or damage on the lifter rod. I wondered if they listed size specs, but seems it's not a wear item like caliper cylinders. It's cool you found it and doesn't seem to be any expense.  You had the answer all along.  |

That's a beautiful bike. I like the rotor covers.

Thanks guys! I'm glad it was not the clutch or the drive line. I went back out and pulled the parts from the cleaner and rinsed the parts. With a little cleaning ever thing look reusable.  I'll run a brake hone on the cylinder tomorrow. I'll dress up the piston with some emery cloth. The only hold up will be if the local Honda dealer has a seal for the piston seal. With luck I should be back on the road soon.  |
