1.If the bike has been sitting for some time the clutch plates may be dry- remove plates and soak in oil overnight.
2. Check steel clutch disks are not warped
3. Clutch has nine friction discs, 8 larger ones and one smaller(the inner or first one you install). Inside this diameter of the ninth friction disc is whats called a judder spring, one flat and one concave, check that the concave faces inwards check that the flat one is installed first.
4. Bleed the clutch as per the manual, in reverse.
5. Check clutch throw with clutch cover off and clutch plates assembled. Watch the pressure plate for movement, should move around 3-5mm.
6. Try a 10W oil instead of 15W(Motul)
7.All else fails, **** the judder spring off! I did this on mine after days and days of rootin about trying to stop the bike walking forward in gear with the clutch in!! and it was much better! Judder spring is there I believe to make the clutch a bit smoother, didnt make any difference to the smoothness of my clutch but it stopped the bike walking forward in gear!
Hope this helps mate!

Clutch won't release on 2008 KTM 144 sx

Make sure cables are working . Follow it down to clutch and make sure clutch lever is actually moving. It is does then pull clutch in and pushbike backwards. Should release If not , plates are probably frozen through excessive heat. Replace them. If lever does not move when clutch handle pulled, then adjust or broken cable. hope that' it, easier and cheaper!

Will not shift into first gear

Sounds like your clutch is out of adjustment, or needs to be bled. Most of the ktm's use a Magura hydraulic clutch which can be bled using Mineral Oil. DO NOT USE BRAKE FLUID.

When I stall my ktm 450 sxf it wont fire again however if u turn it off at the ignition it starts straight away?? What could this be?

Your gonna seize your engine if you keep stalling it, very bad. Also its a switch that incase you crash and the engine stalls it will cut power to the coils located under the tank, to prevent any kind of electrical fire. just don't keep stallin it and let off the clutch just a little slower.
