Try adjusting it only 1/4 turn out from lightly seated. I know the manual says 1/2-3/4 but just give it a shot. Make sure the cable is all the way slack as well and when re adjusting it try pulling the lever and letting it snap back a few times while adjusting it out.

If you've been riding and the clutch is warm it might make a difference in the adjustment.

Also try running the adjustment rod in a full turn from lightly seated then back out again then try to adjust. It helps seat the throw out bearings and plates.

When you put the spring retainer back on which position did you use?  Did you check it before you removed it?   It's got 3 possible positions.  It's been a long time, but as I recall you should start with the middle choice.  Service manual mentions it.  My guess is you've got it in the tightest position.  Look for the A, B and C markings.

michael133

no,i was just reading that and I think I put on different   how do I no rite place

rageglide

a flat edge across the spring when you've got the bolts seated.  Also in the service manual.   When you take the retainer off you can see which seat is middle.  Start there.

My guess is if you put a flat edge on the spring as it is now you'd find it's depressed inward, which limits how far the pressure plate can move.

I see in the book 3 diff setting   low med and high compression...only thing how can I tel where to put can I tell by looking at back that goes to spring

rageglide

What letter are you on now?   It's been about 20 yrs since I screwed with the settings trying to get more bite.  I can't recall exactly which is loosest, but I'd guess A.

Look at the plate, you shoudl be able to see where a bolt made contact.  Try that one.  Flat edge on the spring, spring should be flat. 
(BTW to your how to check plates thread... the adjuster is there to make up for the stack height changes as the disks wear.)

Plus once you do this, you need to loosen up the cable completely, and disconnect the cable from the release lever, set the adjuster and readjust it all again.

 a is mid compression,what un hook from lever on top tranny

michael133

and should it be on greatest compresionwhitch is b  a is mid andc is least

michael133

when I pull the plate off,will I be able to tell  and again when u say cable off do u mean on grip or at on top tranny

michael133

I wont be able to sleep till I get this rite,,,,thats the onle thing I didn't pay att. to when coming apart I didn't no there where 3 pos.  c is least a is mid and b is greatest,,,

rageglide

I had to do some googling cuz I couldnt' remember the letters off top of my head.   A is Mid, B is Most, C is Least.   Start with A like i suggested before.   Check the spring for flatness.  Flat should be good.

My guess is that you're currently using B position which is giving you the problems.

Get the spring pressure stuff adjusted properly with the Cable and release lever adjustment LOOSE.  Once spring is set correct, adjust release lever throw per Service Manual, then adjust cable.   

edit cleaned up an oops

michael133

when I pull off ajust plate how can I tell what its on now,is there ,,is it lettered

michael133

  b is greatest  a is mid and c is least...where should I be at

rageglide

YES you can see the letters.  They are stamped in the aluminum retainer.  Move yours to the A hole. lol   then check it you want the spring to be flat.   

Look at the 6-15 picture from service manual.   Look at the "Concave" picture, this should help you see why you aren't able to get enough throw of the clutch adjustment to release the levers.  The pressure plate bottoms out on the spring if you've got a tall clutch plate stack (ie new or minimal wear).

I've said this about 10 times now.  YOU need to check the spring to know what position to place the retainer.  You want the spring to be FLAT.  So whatever hole is needed is the correct one.

Do you not have a factory service manual??   It explains what you need to know and do.  It's an adjustment that you need to determine.

I'd try the mid like rageglide suggested.

michael133

my manual don't say a dam thing bout where it should be it just shows 3 different setting.and there is no marking on it,sorry.done

rageglide

Look at the post I provided to you with a picture of the ring.  You get a cross section of the ring, That lets you see the height differences. 

There's an A, B and C next to Three of the 12 holes, you have 4 bolts, put one bolt in the A hole, then start that bolt   The remaining 3 will go in correct holes.  Can't mix em up from there. 

If it's working now, you should be good to go.   No it's not going to hurt anything if it's working.  Worst case you will have slippage, in which case you would try a different hole.   You *can* break the release fingers if you kept the adjuster where it was... because like i said already, the pressure plate will bottom out.   

Did you use a Flat Edge to check the spring to make sure it was flat when you mounted the ring?


Here's a pic of the ring and red circles around the A, B and C.  (stole it from a thread on different forum)
