Bike year & model = 2013 EC 300R with e start
Temperature (degF) =26C = 80 oddF
Elevation (feet) =less than 500ft
Main jet = 175
Pilot jet =40
Needle & notch =N3CJ #3
Air screw setting =1.5
Throttle valve/slide =standard ( 7 i think)

Results:no bloody good!
Bike was running OK, with the 0-1/8 splutter.With the 40PJ I could NOT get it to idle at all.I had this problem with my 2010 too.I put the 42 back in-> all good.
Looks like I'll have to accept the slightly annoying splutter/burble and never touch it again!
So, what works is:
Bike year & model = 2013 GG EC 300R with e start
Temperature (degF) =80
Elevation (feet) =500
Main jet = 175
Pilot jet =42
Needle & notch =N3CJ#3
Air screw setting =1.5
Throttle valve/slide =7

Results:back to its normal self.End of quest.
