I decide to finally check the Valve clearances now that I have hit 1000km. They are pretty tight. Exhaust are like 0.08mm, (tolerance is 0.20-0.25) and the Inlet's are at about 0.06mm (tolerance is 0.10-0.15). Has anyone else checked their KLX450 yet How hard is it to put shims in? I don't have a full service manual, but I guess I should probably get one if I am going to do this myself?
