help with idle adjustment

[bjohn07]

How does the slide look? 
The link has a pic of what the slide will look like when the chrome has flaked or
worn off.  (you have to scroll down a tad)   
 This will play havoc with trying to get that carb tuned.   
     (Kind of what happens when  throttle shafts are worn/worn out.)

looks nothing like that one.  looks pretty good to me.  some wear marks but no deep gouges or nicks or anything like that.

[bjohn07]

might be the weather is a little to cold for me to get it right.  its been 45 or lower here.  gonna wait till it gets to at least 65 till i try again.  and i just ordered a new air filter.  the one that came with it looked old and worn even after i cleaned it.

 Well Rats,
 There are a few brave souls racing out there on frozen lakes, so it can be done, I guess.
    There is a bunch of KX500 info posted here: http://media.beta.photobucket.com/user/Friar-Tuck/profile
You do have to snoop around the site some.
 and some more Here: http://www.kxriders.com/coppermine/thumbnails.php?album=lastup&cat=1&page=2

  Hang in there,  You'll get her there.

i think im really close.   this bike takes along time to warm up, like 15 minutes (its in the 50s here) but once its warm i finally got it to idle on its own, the idle screw in pretty much all the way in.  and the idle/air mixture screw is 3 turns out, does this mean i need to richen up my pilot jet?  pulled the plug to check it out after riding, got wot a few times in 3rd and fourth.  plug is wet, not soaked and black, but wet, ceramic piece on plug is still normal color only soaked.  should i come down on my main jet?           

[Friar-Tuck]

 Ideally you want 2 turns out on your air screw, this will give you some adjustment either way for daily weather/temp & elevation changes.   
    The air screw regulates the amount of air added (or taken away) from the pilot circuit.
( see second diagram on page http://www.kxriders.com/coppermine/displayimage.php?album=lastup&cat=1&pos=52 )
   If your a.s. is three turns out from seated, you are "leaning out" the  amount of fuel your current pilot jet
is feeding your engine.     Dropping one size pilot jet  should require you to "turn in" the current position of the A.S.
  to hopefully about..... two turns out!

good thing i asked.  i was thinking it was reversed and i was planning on upping the jet.     so down a size on my pilot is the nxt move.   let you guys know tomorrow evening if it works.  as long as i get out of work on time.

Check this out :  http://beta.photobucket.com/images/kx500%20owners%20man

Look at the chart for around 9600' and around 50 deg (F)  you use a correction factor of about .95

 Does any of that stuff make sense?

[bjohn07]

sorry.  makes no sense to me.     having some trouble understanding that.  that is the same chart in the owners manual in the carb tuning section?

okay did some searching and found this.http://justkdx.dirtrider.net/printcarbtuning.html  helped me get a grasp on the correction factor.

 Hang in there Man,  You'll get her runnin' like a scaulded Dawg.

so i think this has something to do with the bad idle.  been searching and all says your not supposed to see the light.  i already tried flipping them and the gap just opened up a little more.

 Yep, the shin bone connected to the ankle bone, well, you know..
   Most every jetting guide will ask if you've already gone through the bike eliminating anything that could throw a curve at you.     I apologize for not asking all the preliminary stuff    
   Well, Better to find this now than after a month of "Try this or that". 
After you decide on reeds and possibly the spacer maybe we could take it from the top?
