So i have an 03 kx 125. Bike runs pretty good but has a notorious flat spot. It's got the stock mikuni tmx carb and word on the street (or this forum) is that they're junk. I have an extra pwk off a 05 kx 250 laying around that I was thinking about putting on to see if it would help out performance a bit. Has anyone ever swapped a pwk in one of these bikes? Thanks in advance!
