Over 200 satisfied customers.  KTM clutch spring kit.  One new pack of 48 quantity, stainless-steel, top quality, consistent, Belleville (disc spring) washers.  These are of proper spec and not the hardware store junk some others are selling. Made in Germany.  Use these to tune the clutch engagement/powerband for your rider or just replace the weak worn out units.  These are a must if you want to fine tune your machine for earlier or later clutch engagement for riders of different ability and weight or at different temperatures and on different terrain.  See my other auctions for more KTM 50 pro parts.
Below are tuning recommendations from TH RACING at

"I normally setup racing clutches to an overall height of .650 - .690 depending on the rider’s weight and track type.  If you stay in that range you should be happy with the results.  A good place to start would be if your rider weighs 50 pounds stay around .650, 60 pounds .670, over 65 pounds go for the .690 setup.  I am calling the overall height that of all the cupped washers and flat washers together.
Now we get into the options.
A setup that uses a () setup vs a (()) setup.
A () setup will throw the clutches quicker a feel a little more responsive than a setup that used (()) washer stacks.
In the warmer months a () setup seems to breakdown with heat much quicker than a (()) setup.
Suggested Summer setup – (top of bolt on this end)
(())(())(())() plus the flat washers.
Suggested Winter– (top of bolt on this end)
()()()()((((((( plus the flat washers .
It is very important to ensure that ALL THREE WASHER STACKS are of equal height.  If 1 or 2 clutch pads hit the drum before the others you are losing hook-up ability.
