When you say stock jetting, what is stock jetting for a 300 sx? Is it the same as the 250 sx? 35 pilot 42-71 needle in third clip position and 450 main?

Whereabouts are people setting their float height? I've currently got mine around 8.5 but I just wondered if that would make it too lean as ktm recommend around 6.5

If I was being picky with my setup it’s if I crack the throttle open I can bog it out (lean bog) but if I was to go leaner on the needle or pilot it would be over rich, thanks for the reply, I’ll try the settings you suggest and get back to you 👍

Mine is set at 8.6

No that’s fine that is, like I said it runs well with those settings, jd recommend 4.5 on the needle for my bike so I’ve had to go 1 and a half clips richer to make it run right it was more of question of where people are setting there float height and would the settings digger and aj recommend...

Great thread! I have a 2017 ktm 125 xcw and have struggled with getting the jetting right. My current settings are Base gasket replaced 32.5 pj As1.5 Jd blue needle on clip pos 5.5 Mj 460 Slide 4 Nj R8 99 octane fuel 60:1 This seems to work well but I am going to try the settings digger and aj...
