Just got this KX500-E2 and it has a Keihin PJ38 instead of the correct PWK38. I definitely want to put the correct carb back on it especially since the PJ is used on the red bike and the PWK is the more modern carburetor. My question is this..Should I just find a stock replacement PWK or think of changing to something else such as a Lectron or Mikuni TMX. It really pains me to see Keihin carbs on anything but a H***a.
