I just bought a new 2009 and I was just idling it in the garage tonight. AFter getting it upto operating temperature I thought I'd rev it a bit keeping in mind I'm still in the break in stage. So I slowly ramped it up to 4K RPM and held it there for about 5 seconds and let off on the throttle. I could feel a bunch of heat coming from the fairing so I naturally took a quick look inside. Well just as I glanced in I saw what looked like glowing headers that where cooling down?
So naturally I thought I'd try it again, but this time I watched the headers. Sure as **** after about 5 seconds I could see the header get so hot they glowed!!! I couldn't believe it. Then I thought I'd see what happened once the electric fans kicked in. So I let it idle for a minute or so and the fans kicked. I right away got the RPM up to 4K again and no glowing.
So I guess when you're driving its got enough air flow that they shouldn't glow. But holy crap man, how the hell can the exhaust be so hot??? I've never seen this on any bike I've ever owned. I know new engines are a bit tight, but why would a tight motor cause the exhaust to be so hot? I could see the block maybe running a bit warmer, but why the headers?
It almost seems like its lean as hell.
Anyone else ever seen this?
