Carburetor jet changes

Time to change my carb jets.


Pilot Jet #40 removed.
Pilot Jet #42 installed.


Main Jet #120 removed.
Main Jet #125 installed.


Now that covers idle to 1/4 throttle and the upper quarter to third of throtle to full open. Time to richen up the main throttle positions inbetween those extremes.


Needle is non-adjustable. This is the thickenss of the top of the needle permanantly affixed washer.

Not bad, just a hair thicker than the original, just a hair over 1mm additional lift on the needle to richen it up.










I used the smallest washer in the box, top left corner.

EDIT: As a starting position, I set my newly accessable Air Pilot screw out 2 turns and will tune from there after reinstalling the carburetor in the bike. 2 for sea level, 2 1/2 turns for elevation seems to be a decent starting position when not knowing.
