I have a 2007, and when I start my bike up it idles high, which is normal. But after about 20 seconds it drops down very low, like under 1000 rpm. Then after another 20 seconds or so it will go back up to where it was when I first started it. Then once it warms up it will idle @ about 1200RPM which is normal. I also experience this sometimes when I am riding. Sometimes I pull up to a light and it will idle at like 800 rpm, then sometimes at 1200-1500RPM? Anyone else experience this issue? Thanks.
