Mixture screw question

[rusty_num2]

Which way is lean/rich when adjusting the mixture screws? Is there any way to remove the brass plugs without removing the carbs? I'm new to this whole bike engine stuff.


Thanks,

I dont think you can remove the plugs on the bike (not enough workspace)  but if your going to pull off the carbs I'd say rejet it too. ($10)   have you read the howto on gstwins.com ??

the idle air screw is 10 on the rejet page.  
but screwing it out is rich, screwing it in is lean.  If its stock it is going to be 1/2-1 turn out.  

p.s. dont forget you have 2 carbs.

It isn't an air screw, it is a fuel screw. You do have the direction right, but if you understand it is controlling the fuel flow, it makes more sense.
