[QUOTE="03HiYoSilver, post: 271113, member: 3137"] I thought some would like to look at the head/valves of a FJR with 37k miles. Mind you, I don't think mine falls in the Normal category since it always seemed to run rich, even after the head replacement. I have had it for about 10k miles and only run top tier gasoline and usually 93 octane. My next step is to probably install RIVNUTS to test the CO balance across all four cylinders so it won't look like this again.
