Which TMX is it?  There are 2 styles. The original tm and the tmx from a CR250?

Is it lean or rich? I can tell you what my jetting is but it is on a ported stock cylinder. 32.5 pilot, stock needle on the 4th clip, s8 nozzle, and a 390 main.

I got the specs from Pro Circuit website on an 02 cr250. The 01 and 02 use he same needles but the 01 uses an s9 nozzle and the 02 uses an s8 nozzle. The nozzle or needle jet can richen or lean it without changing the taper of the needle.

The 03 uses different needles and I think a different size slide. Pro Circuit says to set the 03 up like the 02.
