air screw setting increments for safe p. chopping

[Escobarclan]

Hey guys.

82' 1000 Kat, pods, mtc open header 4 into 1. Stage 1 back in, used to have a stage 3, didn't run too smooth though.

Checked my plugs, running lean, as in crisp white. I would normally plug chop her as I turned out the air screws, but I don't want to run her so lean and create an expensive problem. Can anyone tell me how many turns I could back the air screws out from where they are now (2 1/2), to make it safe enough to take her on the road and plug chop her?

I know this is a shot in the dark for you guys, but I guess what I'm asking is what increments could I use to get her away from lean quickly. 1 turn? 2? I would rather be rich to start off, and trim the fuel down, you know what I mean.

Backing the screws out will add more air, thus making it more lean. Turn them in to decrease the air, and richen the mix. Probably 1/4 to 1/2 turn, then recheck.

Holy crap. I've always thought turn them out increased FUEL. So the 'air screws actually control air? Like as in vacuum to increase or lower fuel? never messed with these much until recently.

CV carbs. Out to richen.

cool, thanks

I have had VM carbs on the brain lately, didn't even think about your bike having CV carbs. But if I understand the cv carbs, you are not controling the air, but instead the gas. So therefore clockwise leans the mix, counterclockwise richens the mix.

ok, thank you. gotta get this lean problem fixed.
