Re: yamaha carbs

Back off the idle screw to where its not touching anymore. Loosen the follower cam screw and the adjustment screw on the upper carb. Both screws turn right to loosen, not left like standard. You'll see the arrows. Make sure both carbs are fully closed and tighten the top screw, then readjust idle. Last readjust follower cam.

Re: yamaha carbs

Book calls for 5/8 turns +or- 1/4. Just do it till it feels good.
