I have bought a 2016 300exc, stock apart from a KTM pipe.
It's running rich at the bottom end and then runs spot on from about 1/8 throttle on.
I have fitted a 35 pilot jet, it's helped but still seams rich.
I can screw the air screw all the way out without the tick over slowing, all this points to a smaller pilot jet but it already seems small, Any thoughts.
I'm running 60/1 fuel mix as per the manual is this what most people are running?
I,m just using it for green laning.
