Clutch Drag is often problem on KTM EXC models, but it also affects other bikes like Yamaha, Honda, Suzuki and others. In this video i am going to show you how to fix sticky clutch with Coca Cola and Sand Paper. This is going only to work if your problem is in inner disc , if you have problem with basket then you need find another solution.

Just as an additional information to anyone trying this after watching this great useful video, just finished servicing a Husqvarna FE 350 3018 that had the same problem and my method was using an orbital (round) sander with very fine grit (was 120 but anyway when you start working it it wears out pretty quickly so it's fine too).
The way to do it is having a perfect flat thick glass, then an A4 plain sheet of paper, then apply a mix of oil/gas on a used window cleaner bottle (great way to apply to many components on dirt bikes to keep them fresh), then sand each side lightly while rotating the discs. (Only the metal ones). (Very important to keep orbital sander flat, with very light pressure).
It is important to take out the glaze off the fiber bits by hand. (Use those super fine pads for car body spray-paint preparation). You can also use the sander if you have good control. (When I did it, I was turning it on and off. No need for excessive speed).
Done this after 24 hours gas immersion bath on the components. You can use this gas to wash the dirt as you go along and treat each of the clutch plates.
Also very important, do pass (manually) the outside of the metal plates over the super-fine sanding sponge (with oil/gas mix as well) to make sure this edge is smooth. For the fiber ones, this process is on the inside.
Before assembly, wash everything again with plain gas, and then let them soak for a few minutes in the oil you use on your motor.
Tested the bike. Very good! No clutch drag (or lock?...) at all.
Beware - this method saves having to buy/replace clutch plates at least one time. But definitely have a set ready to replace just in case you find that wear is excessive.
Pay attention also to the damping rubber bits on the back of the DDS inner hub. Recommend having a set of these ready to replace as well if there's too much play in inner-hub.
Best regards, safe (extreme) rides!

I think your pink spokes are causing the flux capacitor to overdrive the clutch, try a different colour

The difference between the Before and After is also that the bike was at operating temp when the problem was present and cold when it wasn't. You need to have it up to temp and check to see if you still have the clutch drag.

It worked for me. But I think I have sanded too much since the bevel spring does not stay flat. But it's working!

just soda blast the steels, i run less torque on the inner hub nut.. also drilled more holes in the inner hub to promote more lube into pack.. measure your clutch pack stack/height too... make sure you're not past spec making a bigger clutch pack in ther, ran some washers on the clutch spring bolts for less clutch finger pull too!

Had the same problem on my Beta. I sanded the plates, installed the stamped curved side out for the plates and much better. No soft drink dip though lol. Not sure how long it will last until it polishes up smooth again. Some clutch metal plates have small indentations for the same reason. If the drag comes back I will employ coarse sand paper and teach it a real lesson!

I have a desert racer friend who rubbed his clutch plates in sand two at a time against eachother, then he cleanend them off and put the motor together and came in second in a race with 1000 people in mattawa washington. Kevin Bise is the guy who did this.

Hello, Did you sand papper both sides of the plates? Should the sharp side on the plates be outside when you replacing it? Can i use 1200 sand paper or should i use 400?

I’m new to Ktm and my 25 300 XEW creeps forward but I’m told by everyone this is normal for wet clutches. It’s supposed to have some slight drag.? it made it even worse when I added Shorty lovers because then the amount of adjustment is even less so it’s really critical and now I’m worried to potentially burn out my clutch and not sure how to adjust it but it seems to me you need to adjust it when the clutch is hot versus cold.
