While I was adjusting my valves, I noticed that my cam lobes don't have that ultrasmoot, mirrr-like finish that they should. instead, the entire surface of the lobe (including the rounded back end) has this cloudy, discolored, rubbed look to them. Then I am seeing the very beginning of some pitting on one lobe (a minute pin-hole or two). My old ninja had deeply pitted cams, yet ran like a champ. I was just wondering whether this is normal for the gixxers. I'm hoping that my good oil changing habits, along with semi-synthetic Motul, will stop this wearing process that started with the previous owner. Anyone have experience with such things?
