Hi Guys, I have a 1997 KX100 but It has the 2001 and onwards Carb fitted (Keihin PWK-28) but the previous owner put the jets from the 1997 Carb (Keihin PE-26) into this 2001+ Carb. The problem is that they both use different jets. The 2001+ Carb is meant to have a : 138 Main Jet 45 Pilot Jet 'NAPF' Jet Needle 60 Main Air Jet But my 2001 Carb has : 122 Main Jet 55 Pilot Jet (I tried to read the Jet Needle) : NBKF No idea but probably 200 Main Air Jet (That is what the 1997 Carb would have) Temperature would be 10 Celcius on average roughly. The bike is standard. What Jetting would you recommend? Thanks and ATB!
