Maintenance & Technical > KX500 Original
Need new pipe-want more RPM
Johnniespeed:
The original pipe was damaged in a crash or I would try that again. The Gnarly Desert should be here in a week or two and we will try that and report back. When the April rain stops the trails will dry out and I can get out riding again.
Has anyone tried the Dunlop MX31 sand/soft tires yet ? The Dunlop 733 tire has been dsicontinued so something else must be used.

Sorry cant really remember mate, i was only concerned with more top end at the time, so i didnt really pay attention to much else. Also i didnt have much ride time at all befor the piston pin clip broke on me.

:roll: The top end wasnt destroyed as a result of the carby, it was just unlucky that a piston pin clip broke.
I havent even heard of this happening to anyone else :x

I usually only make one change at a time, but this time I changed a bunch of stuff. I took off the D773 tires and changed to MX31 tires, I took off the reed spacer, I installed the V-Force 3 reed cage, I removed the Gnarly Woods pipe and changed to the Gnarly Desert pipe.
I lost a small amount of torque at off idle/ low rpm, but the mid and upper rpm have improved greatly. It was raining today and I was unable to ride the bike to its full potential but the power gains were great.
The Gnarly Desert pipe fit much better than the Gnarly woods pipe. On both pipes I had to grind and file the gasket surface to get the pipe to hang by the springs in correct position, then I bend or shim all mounts to secure the pipe without adding any tension. The Desert pipe fit a lot better than the woods pipe.

Oh I forgot to mention, that with the Gnarly Desert pipe I was able to move my kickstarter back to the original position, with the Gnarly Woods pipe, I had to move my kickstarter a spline or two to prevent it from hitting the pipe. I was very happy to be able to put it back in the correct position.
