help with idle adjustment
Hillclimb#42:
did you fatten up air screw? as cold as it is here, it would be lean. air screw would likely need to be all the way in, or like mentioned, increase the pilot size. Adjusting the cable to get an idle is bad, really bad. It can make the bike rev, when you turn the bars, or can even caus the motor to rev out of control just sitting there. the slide closing helps kill the motor in the event of an air leak or ring heating up during seating. Also could be slide wear where the idle screw makes contact. Im guessing freakin cold is makin the k5 unhappy...

Ill try to fatten up the air screw today. If not im hoping apex stocks the pilot jets
bjohn07:
air screw didnt work. so i picked up a 62 pilot. once it was warm it ran a little better than before but still wont idle. :-( not sure where to go from here. dirt bike carbs are way harder for me to grasp than good ol 4 barrels.

This article I wrote might help you learn a bit about your carb.

If you find anything useful, or confusing, let me know.

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.)
