Idle or not Idle?

I gotta ask how on that one. All idle is is a stop that doesn't let the slide bottom all the way. Shouldn't change throttle response unless they set the air screw differently. Am I missing something?In my pro days I always wanted an idle so you didn't have to restart if you fell off. Cam.

Exactly, especially when hot and muddy! There is nothing worse than a muggy hot day in the mud being roosted in the face trying to restart your bike.
I used to race alot on my 250 and always kept an idle. What I don't like is stalling in the air off a 100ft double!!!

After speaking with several engine tuners I stand corrected. Sort of. The CR500 (the bike I had before the KX) runs older style PJ Keihin carburator that incorporates the idle adjustment and the choke together. This makes for a delicate balance between proper idle and flooding the motor with fuel when the throttle is opened up...On KX's with the PWK carb, this is not an issue. Some mechanics still set the idle to 0 to be sure that the motor does no overrun when going into corners. Set your idle where you want it, and don't forget the wasabi.

I like when a bike idles.. it sucks when you are trying to adjust your goggles or something of that sort and the bike putters out on you. Think about the races with the 2-strokes and some 4-bangers where the mechanic/riding coach is at the the starting gates and has to keep the bike running for the rider while he is getting ready. Unless you are seriously into racing and ultimate performance, the idle/no idle is a pretty insignificant power issue I would imagine (but I don't race).
But as far as the idle issue on my bikes? I like idle. I just got my KX5 motor/carb back from the motor builder that we all use here in Vegas. I did a reinforcement mod to my rads in the meantime and should test it on the next trip with a report to follow. Anyway, I put the bike back together, added fluids, and the bike started on the second kick ! Warmed it up a bit, shut it down and restarted it a few minutes on the first kick. Now this is not a stock motor anymore. Head decked with thin squish for higher compression, ported cylinder and intake/exhaust ports. The PWK was ported to about a 41mm with other custom work that is semi-secret to the builder. If you hold the carb up to the light you can see through on both sides of the slide. So with that being said, I didn't even adjust the idle screw from the position I sent it off at and the bike selted down into a perfect purr of an idle. Did I mention that I like idle :roll:
Just some reteric from myself... Sly
