I have a 2005 klr 650. After it warms up, when I pull in the cluch to shift gears, the idle speed doesn't drop right away. Just wondering what is causing this. Also, what RPM should the idle speed be set at?
It could be a lot of things. On a 5 year old bike, I'd suspect gummed up stuff in the carb. The circuits could have some gum or varnish in them, the slide might be a bit sticky, and such. The easiest thing to try would be to run a dose of Seafoam through the thing and see what happens. If that doesn't fix it, you're probably going to need to dig into the carb and do a rebuild. Worth a shot.
I have mine idling at 1,000 rpm. I think spec is about 1,200 or so.
