stpauls Posted June 7, 2016 Share Posted June 7, 2016 (edited) My 2014 Sherco ST 125 is running a bit rich. Do i turn the mixture screw clockwise or anticlockwise on the Keihin carb to lean the mixture? Thanks Edited June 7, 2016 by stpauls Quote Link to comment Share on other sites More sharing options...
twinshockdude Posted June 7, 2016 Share Posted June 7, 2016 if your spark plug is sooty you need to drop the needle,one notch may be too much.you can buy a spacer from splat shop which makes half a notch adjustment possible,the mixture screw only affects the first part of throttle opening.
