89 clutch issues tried the regular fixes. Now what?

I'm having this haunting issue with my new to me 89 clutch.
It doesn't dissengage fully, in fact it barely lets me go forward without revving the heck out of the engine then leaps forward when I shove it into first.
This sounds like sticking clutches, but I soaked them all in trans fluid,
SOunds like buggered basket but I filed down the high spots.

I'm thinking it's my lever or my actuator. When I turn the actuator with a wrench more than the clutch lever pulls it engages the clutch and I can shift just fine. I have adjusted the cable slack to spec or tighter, and have welded and reground the actuator and pin to a tighter tollerance to no avail. I think I have an aftermarket lever on there, is it possible it isn't pulling enough, I'll take some pics.

It is teaching me to be a smoother rider though......

Looks like the push rod is not shimmed correctly. Do you have any washers on the push rod in the center of the clutch? If so how many?

Yes I have one and I have built up the rest of the pushrod with weld and ground it to take up the rest of the slack in the shaft/pushrod. There is space between them when the clutch is released but not much at all.

There should be no space at all. Are you missing the large flat washer under the basket?

as in between the back of the basket and the case? it's there. and so is the one inside the basket.
Does the amount of lever movement seem like it's enough?

Cable does not even appear to be tight in this picture

Not sure that jerry-rig is gonna work very well

This is more like what it should look like

Are you adjusting it it here first?

There and on the lever itself. How tight is that cable suposed to be? The lever has about 2mm of freeplay before the actuator moves.

The actuating arm is at rest in the wrong place. Welding up the rod was probably a bad idea. The rig job for cable holder looks ok, but you need to be able to adjust from there as well.

On my KDX, I've never been able to have any free play at the lever whatsoever and have the clutch not slip

maybe my basket is still buggered, I'll take it for a good ride and see if it smarten's up
Wibbens, I did tighten the freeplay all up and did have slipping issues so I'll bet that I'm at my limit there. I did that just so I could get the clutch to dissengage.

Probably has more to do with your cable set up than anything

Ok so some progress, I welded and ground a ramped profile into the actuator which is normally flat and have made a decent improvement. I think I have to go a little more to get it just right. Basically what this is doing is pushing the actuator pin more than stock. The actuator was welded like this when I got the bike and when I tried to make it look stock again I guess I buggered that profile up.
I can still stall the bike with the clutch engaged but it's much easier to keep it running with a little throttle. so i'm on my way.
I also have a new clutch cable coming this weekend.

Side note: I am looking for a good used clutch basket, and I will get a new actuator and pin when that happens, so this is a band aid fix for now.
Are all the baskets 89-06 the same?

89-94

Looks like they changed the design in that time period, as the later ones look beefier, what do you think of this?

see the difference between that and the 89?

I think there is a thread on here about some one using an H basket on an E bike. Might be worth a search. I think it had something to do with an auto clutch if that helps.

Looking at Mr.Wibbens' photo's before I go out and get a basket I'll follow the cable advice and make damn sure it's dialed perfectly. I suspect I have more effective cable pull losses through the old cable setup as Wibbens suggested. I'll let you all know how it goes down this weekend

An H basket will mate up properly with all the gears and such, but because it's a different diameter, you need all the H plates and the H pressure plate and hub. So you'd have to get the whole assembly. And once you get the whole assembly in there, I'm not sure the E clutch cover and actuator arm would work with the H clutch.

Definitely get an E basket, 89-94.
