150 main jet kx 250

Recommended Posts

I purchased my first bike (2001 kx250) alittle over a year ago from a buddy at work. He claimed it was a big bore but he had forgotten what the displacement was.

I tore down the carb to clean it and check out the jets. So here is what I found.

150 main

42 pilot

Naff needle on the 2nd clip.

i know for sure its a big bore now but still unsure of what size untill I do a top end this year. She runs great and no need to re-jet.

Just out of curiosity whos running similar jetting on their big bore kx 250s
