I have an '05, 9.5k miles on it. All is quiet until it hits 3 bars. As soon as the 3rd bar illuminates, the valve noise gets very noticable. Let it cool back down and valve noise completely disappears. Can't decide if this is just the "typical valve noise" or if it is signs of a ticker in developing. With temps in the +90F range, my '05 quickly jumps to three bars and sits there all day. Yes, it is abnormally hot this summer; however, I'm getting tired of the valve noise.
Of note, just when I think the valve noise is getting "bad", I pull next to another bike and quickly get put back in place. A newer CBR makes at least 2x the noise. And Buell should be ashamed of the valve noise coming from their XB9 engine. Those bikes make TONS of valve noise. The FJR tick is a whisper compared to those bikes.
Funny story on the topic too. The other day, I'm riding home from work and thought for sure the ticking had settled in right there at a stop light. I thought a valve was going to pop straight up, spin a few times in the sky, and land right in my lap. As I pull away, I realize that the ticking isn't coorelated to my engine rpm. Look in the mirror to see a POS Nissan econobox had inched-up to my rear tire while waiting on the light. With blue smoke bellowing out it's tail pipe, it was only then did I realize it was the source of the ticking *LOL*
Maybe I should just take chill on the whole ticking thing *shrug*
