Really enjoyed reading this entire thread. Bike looks great. We just finished completely rebuilding a 2003 KX125 from the frame up for my son.

He's only 14 but 5'10"...

We did everything Eric Gorr recommended, Pro Circuit Pipe with Shorty 304 silencer, Vforce3 reeds, left jetting at stock setting. We added a 7oz fly wheel weight.. According to...
