08 KLR engine rpm issue

When closing the throttle to shift, my bike rpms are slow to return to idle. It runs fine except for the annoying delay in rpms returning to a lower level. It does this also when not moving and I rev the engine. It will finally lower, but take a few seconds. Any suggestions?

That sounds like a lean condition. If you haven't made any changes to the bike in awhile, I would suspect a minor blockage in the pilot jet or maybe just $#[email protected]@y gas.

Lazy options: You could try running some carb cleaner through the gas or just ride the crap out of it.

A more comprehensive solution would be to clean your carb/jets.

Ron T,
I will suggest to Loosen the throttle cable slack adjusters, 1/2 turn each.

If that does not do it, go ahead and run some fuel system cleaner thru it. I think Chevron Techron is one of the best. But if it currently does idle and respond to throttle, I think it is lack of cable slack.

Modify at "YOUR OWN RISK"!

It might be that the slide in the carb is sticky and hanging open. The slide on the KLR is not directly connected to the throttle cables. Instead the cables open the butterfly and vacuum opens the slide proportionately. That is why the KLR is a little sluggish compared to some other bikes that have directly connected slides. If the slide has gotten dirty or oily(should be clean and dry,no oil) it may be reacting slowly causing the rpm to react as you have described.

It's not a Tractor....It's a LOCOMOTIVE!! Chugga Chugga
Woooo WOOOOO!!!!!
