Pilot jet adjustment

[lodown]

I've been trying to find out the setting for the pilot air screw. Do you turn them out till you get the max rpm at idle, or in till you get the minimum rpm, and then adjust the idle screws for the correct idle? I'm not sure what side of the scale i sould be on.

2-2 1/2 turns out is a good starting point. turn the until the idle is close to peak and response is crisp.

Thanks for the reply, I wasn't sure if it was when the rpms just started to drop or just started to rise i didn't want the fuel mixture to lean.

Here's how you should turn'em:

Turn the air screw all the way in, just until it's lightly seated, then set it 1.5-turns out

Slowly turn the air screw in, then out, until you find the fastest idle

If the air screw is less than 1-turn from Closed, it needs a larger pilot jet

If the air screw is more than 2.5-turns from Closed, it needs a smaller pilot jet

Once you have determined and installed the correct pilot jet and tuned the air screw for the fastest idle

Set the idle back down and ride the bike, using Closed to 1/4 throttle positions

Turn the air screw slightly (1/8 of a turn) in either direction until you find the point that gives you the best response when cracking the throttle open
