I put a new iridium NGK plug in my Foreman and did a plug chop on it. It appears that it's running a bit lean so I need to fix it. Anyone know how to richen my mixture up a bit?

Assuming you started with a clean carb....

If the chop was at WOT change the main jet; one size larger

If at half throttle lift the needle (drop the clip) one notch

Beware that iridium plugs take a longer run before the chop to get a good read.

Well I got it fixed by adjusting the air/fuel mixture screw and now the plug is a nice caramel color and no more backfire either.
