[QUOTE="DougRoost, post: 1184395, member: 23019"] ...and to help determine pilot jet size you start with the air screw. It should be at 2 turns out to run crisp, plus or minus a half turn. If you can't get it right by adjusting this, you then change the pilot. Since this is metering air instead of fuel, if you have to turn it more than about 2.5 turns out to see improvement, then you're needing to lean it out, so go with a smaller pilot jet and repeat. With a properly jetted 2 stroke, a 1/4 turn can make a big difference in bottom end snap when the temp or humidity changes. Once you get this right, you can get to the needle, which makes the biggest difference since it is where you spend most of your time riding. [/QUOTE]
