I completed a valve check at 12,000 kms and found one valve out of spec. My symptom was the bike was getting harder to start (turning over more than normal). I do not know why at 600 miles but I would not leave it until 15,000 miles, even my manual say 15,000 kms (or 9375 miles)...Thanks! I read the comments after the review. Someone posted " KLR valve adjustment at 15K miles- not if you know what is good for you- more like 600 miles for the first adjustment."
Can someone elaborate more on this because it's the first time I've heard of it. Noob Here!:60:
