1996 rm 125 has clutch problems. The quater inch play does not work, new cable, aftermarket clutch with springs,fibers,steele.

Usually it would fit not together if it wasn,t right I found on my bike that the oil I used was to thick and was causing fast take of slip I ended up mixing to different oils together to get it good thats after two clutches

when you replaced clutch plates did it compress up when you fitted the end plate with springs , also did you soak the fiber plates for a couple of hrs before fitting ! on the end clutch plate is there a centre nut and screw that you can adjust the free play and did you reset this ?

The cable may be binding or the clutch adjustments may be wrong; there is normally two adjustments that have to be made if it is a cable style clutch.

1. the first adjustment will be on the engine near the clutch push rod and normally has a screw and locknut that is to be adjusted. Turn the handlebar adjustment first all the way in so that the cable has a lot of slack in it. Untighten the lock nut from the lower engine adjustment screw so that it does not interfere with the adjustment screw moving. Turn the screw inward until a very light tension is felt on the screw, then back it out about an 1/8 inch or so. tighten the lock nut back down and see if the locknut and screw together will rotate about 5-10 degrees when turned (this adjustment must not be so tight that it can not rotate when checked or it could cause clutch slipping so make sure that the adjustment screw rotates some after the locknut is tightened.

2. The final clutch adjustment is made at the handlebar. Turn the adjustment screw on the handlebar out until the clutch lever has about 1/8 inch of movement (before any tension is felt on the clutch lever) when the clutch lever is first being squeezed. Do not make the 2nd adjustment without any slack in the cable or the clutch may also slip.

If this is a hydraulic clutch and it slips at high rpm, the clutches could be getting hot, the springs are wrong for the clutch, or the clutch and steel fibers have the wrong installed height for the clutch hub (check the original clutch fibers and steels against the new ones installed and see that they are the same thickness or look up that fiber/steel thickness in a service manual).

You may simply just need to adjust your clutch cable. Make sure it feels like your pulling on something, there should be some resistance. Since you'll be adjusting it while the plates are cold you need to leave some free play in the lever or when your clutch pack gets hot it will start slipping and you'll end up with a smoked clutch. What I mean is grab the lever and pull it in until you start feeling resistance and then adjust it our until there is maybe a quarter inch of free play. Hope it helps. If its not that then you've got some internal problems with your plates and fibers not separating correctly.

Clutch dragging / slipping? you need to have free play in the cable the lever should not be tight up against lever holder there should be a loose gap.

did you torque the spring up when you put them in and did you put the push rod in the middle |???

Did you adjust the clutch cable? Have you replaced the springs in the clutch baskit with new one?

The clutch springs are not the problem. Check to see if all parts were installed as shown below. The clutch plates alternate Fiber/steel/fiber/steel, starting and ending with a fiber. Be sure the teeth on the clutch rack are pointing to the rear.

I am going to stick my neck out here and hope I can help.
The springs are not at all likely to be the problem. Any chance the cable is hanging up and not releasing fully? Disconnect the cable at the gearbox, put the bike in gear with the motor not running and see if the motor puts a major drag on pushing the bike. If pushing the bike makes the wheel lock up or the engine turn over it tends to say the cable is bad.

It could be you were given the wrong hub. Compare the old hub to the new one. Do the various measurements match? Contact the dealers parts department and ask how many fiber and how many steel clutch plates are in your clutch. Did your 9 year old son play with a funny looking frisbie and leave it in the back yard?
Ask what plate goes into the clutch hub first > Fiber or steel? Did you install the plates that way? Did the outer clutch cap go on properly and rest against the outer plate? Do any of the fiber disks have a gap wider than the other disks?

Food for thought. I hope this helps.
