'93 Clutch adjustment

Postby dvcruz » Thu Jul 14, 2016 11:13 am



Hi.
I know, there is no adjustment on the 1500's. However...
On my new-to-me bike, once I have the clutch pulled in, drop the bike into 1st, all I have to do is think about releasing the clutch and the bike starts moving forward. It is that sensitive. I've been riding for 40 years so please no advice on how to use a clutch. It is really that sensitive.
Also, trying to get it back into neutral is all but impossible. It will jump into 2nd, then I have to try to push it down to neutral, but it goes back into 1st and on and on. It is really hard to find the sweet spot. Sometimes I have to turn the engine off and "rock" the bike back and forth to find neutral. Again, please no advice on how to properly shift a bike.
I flushed out the system when I got the bike, refilled it and bled out all the air. I didn't touch the slave cyl though.
So, something somewhere needs some kind of adjustment, but I don't know what.
Any thoughts?
Thanks.

sounds like your not getting full pressure to the slave, sounds like you still have some air in the middle of the line somewhere
did you bleed it by pumping and releasing the pressure or letting it gravity bleed
personally I like to let mine gravity bleed, takes longer but seems to work good
when you take your master cover off and watch the fluid when pulling the lever can you see the fluid moving and returning
through the little port in the bottom

I used a Mity-Vac and tied the clutch handle overnight. Took two days, but pretty sure I got all the air out. I'll check again. I'll also take a look at the slave cylinder since I haven't done that yet. I'll pull the master cover off and take a look.
Thanks.

Your clutch lever bushing (should be no play or wobble) along with lever pushrod and/or bushing if worn will cause partial disengagement presenting shifting problems and early engagement. Lots of bikes have worn lever and pushrod bushings due to lack of regular greasing.
This is what I do
Local and need repair help with your 1500, Valkyrie or ST please PM

+1 on the brass bushing. Sounds worn out to me, since you are apparently not getting enough clutch pressure to disengage the clutch, and premature contact on the way out.

You need to bleed the master and slave as a unit to get the air out of the system.

Hi.
Just wanted to close out this thread.
I ended up taking off the slave cylinder and giving it a good cleaning. It was totally gunked up with old brake fluid and I was surprised at how well it cleaned up. Looked like new after only 30-40 mins work.
Once I reinstalled the part, I had a devil of a time bleeding all the air out. Took about 5 evenings of working with it to finally get all the air out. Initially, I used a Mity-Vac, and then my brother, and still couldn't work all the bubbles out. In the evening, I would tie up the clutch lever at night and hope the air would rise out during the night. That trick usually works with brakes.
After 4-5 days without much luck,I finally figured out that the handle bars weren't turned to the right far enough to put the master cylinder all the way to the top of the system. Also, I started running the bike for about 5 mins, pumped the clutch lever many times, squeezed it tight and then the air bubbles really started coming out. Running the engine caused enough vibration in the hoses to loosen up the trapped air bubbles. After only about an hour, I finally got all the air out.
So, after all that, the clutch is working fine now.
Thanks to all for your input.

It's kind of after the fact now but what works well in a case like yours is to bleed at the banjo bolt on the slave first, then the slave bleeder valve next and finally at the banjo on the master. You can get all the air out in only a few minutes this way
