High idle, no idea - Page 2

It's very possible. I'm just trying to avoid costly mechanic work. Might be the only solution though.

In the service manual, download available on this forum, On pg's 108 and 109 there are references to position and how to uncap to adjust pilot screw. If your's is capped then stop.
Wear out other potential failures first.... This is not a first resort diagnostic...
However.
IF your carb has signs of tampering.
And IF yours is already uncapped then I'd recommend getting a real nice fitting small screwdriver and slowly and gently tighten the pilot screw counting EXACTLY how many turns it requires to be fully seated.....
Clockwise.... Gently till it stops...
Don't screw that up...
Right that count down...
Then back off to where it was.
If somewhere between 1.75 and 4 turns then just return it to stock position.
If not in that count then still return to stock position and report here.

Again... Only do this if carb looks tampered with. Otherwise DISREGUARD..

One last warning.
If you're not comfortable trying this. DONT.
You can't blow your motor up but you can make it less usable than it already is if you don't respect the pilot screw and the service manual.
That being said. It's a simple procedure. If you f up then just seat the pilot screw gently and back out about 3
turns. (your results and your carb casting may vary)

Well upon trying to adjust the pilot screw, it's seized up pretty good. I don't want to strip the dang thing. *facepalm*

Spray some WD-40 into the screw that should help break it free.A good starting point is 2 1/2 turns out from lightly seated.Than with bike idling warm (choke off) adjust slowly to fastest/smoothest idle.
