here's an install on an R100 GS. while it's not a KLR, the procedure is similar. http://www.gunsmoke.com/motorcycling/r100gs/gold_valve/index.html you'll have to pull apart the forks and drill new oil passages in the stanchion tubes. same job as installing new fork seals, except for the drilling. good time to install new fork seals if needed. factory oil seals seem to be preferred. "Leakproof" brand are anything but. you'll want a magnet or parts grabber for when you fish the Gold Valves out of the forks to adjust them. to do that you just need to remove the fork cap, spacer and spring then you can remove the valve. i've gotta get them for my street bike when the budget permits. it needs the forks rebuilt anyway.
