What are you guys setting your idle circuit adjustment screws at? How does the plug look? I am currently at 3 and 1 turn(s) out on mine with 27.5 pilots, and would like to richen up the idle mixture a tad. Turning the screws "in" seems to richen up the mixture.....can anyone confirn this? Thanks!!!

Turning the screws out is richer and in is leaner. Rule of thumb is any more then 3 turns out and you need to go to a bigger pilot jet, any less then 1 turn you need to go smaller, Im thinkin of tring difrent size pilots in each carb as I'm at 1 turn on the left and 3 3/4 on the right, going biger on both would put me way down to nothin on the left one.

I'm not positive but I believe the stock setting is one turn out on both carbs. That's what I found when I rejetted for Dumont Dunes (sea level). My dealer claims that they only changed the main jets for the altitude here in Denver.
