Ok .... today's piece of (probably) useless information.
I have had endless trouble with kickstarts on the KLX since rebuilding the motor. Even with new knuckles (old lever) they destroy themselves fairly quickly.
I have just fitted a nos genuine Suzuki TS185 lever complete. Part # 26300-29302. Perfect fit on the splines, and a better shape both in fit and use.
Hopefully I will be back sometime soon to tell you it has not bent, and has not destroyed itself.
Next time I rebuild a motor, I will leave the compression as it was meant to be !
