1998 KDX 220R assumed stock jetting. I have read Canadian Dave's Carb Tuning guide and am planning on jetting my bike over spring break as it it running RICH. Wet fouling plugs very black and oily, blowing lots of smoke (bliush, white), etc. The bike is on my property 2 hrs away so I have no idea what jetting its got now - just got it. It might be nice to go ahead and get some jets.

Can anyone make a good suggestions for starting point and which way to work or should I could go with the CA Dave starting suggestion? since I am located in Houston, TX, I figured suggested jetting may be a little different than the wonderful Canadian climate. Assume altitude less than 500 feet above Sea Level, >70 degrees, and mucho humidity. Gnarly pipe and airbox mod, running 40:1 Maxima oil. Boyeson Reeds to follow later
