Forgot to add from my previous thread, my bike is pure stock, no modification as far as the 1st owner. I only added a slip-on exhaust. But the sputtering is already exist before I added the slip-on.
Correct. I believe most Dynojet centers try for 13.2:1 air/fuel ratio as that is suppose to be optimal.With 13,1-12,9 Air Fuel it is better.
If too lean, then very aggressive the gas assumption.
Mit 13,1-12,9 Air-Fuel ist es besser.
Wenn zu mager, dann sehr agressiv die Gasannahme.
