Carb setting XBR
« on: June 17, 2022, 12:57:26 AM »
Bike is running OK but is running a little on the weak side.
Thinking the pilot screw on the bottom of the carb would be able to richen the mixture and if so do I screw it in or out?

IIRC correctly and it's on the engine side of the carb like my 250RS it controls fuel not air so screw out to richen. But that only really has an effect at idle.
