On the 08 beta rev3 with a Keihin carb which way is rich and which way is lean on the fuel-Air Mixture Attachment?

Thanks

Turning it out would lean the mixture.

Try altering and keep having a look at the plug this will tell you which way is lean or rich! black for rich light brown for lean! Any way when we out on them!

Lean or rich, you don't need to know. Set it by feel!

Set fast tickover. turn screw until you find where engine speeds up slighly, thats the spot.

However if you then check number of turns out from closed and its either half a turn or 3 turns or more then a diferent size pilot is needed.

Set this up on a mild day - it'll be diferent when the weathers really cold
