KX 144 Jetting

[jleblanc321]

I am considering getting an Eric Gorr 144 cc big bore kit for my 1999 KX125. I my case, I have a Boyesen Rad Valve, Pro Circuit pipe, and live at sea-level. I also just ride on the local MX track for fun-no racing. What would be the jetting recommendations for this setup if I use premium pump gas? Also, should I ditch the Rad Valve and PC pipe and get something else, such as a V-Force and FMF fatty pipe, which appers to the recommended setup.

Thanks,
Jay
