hi my ec 300 2004 have this setting men jet 175 . needle N1EF . 3 from top
slow jet 35 . slide 7 . end air screw 0.5 turn from full close the bike run good but not perfect
I would go to at least a #40 pilot and get the air screw out to 1 and 1/2. Where are you located and what are your weather conditions?
when i bought my 01 300 it had a 35 pilot in it also...
les at ltr told me that was oe jetted for leaded gas...
I had never seen a pilot jet that small.
42 in mine...
as gg27 says depending on where you are..
