As I said there isnt a Jet kit out there. You kinda have to improvise and get the specs on the oem part from kawasaki.com and look under the 07 klx 250 they use the same carb. I went with a slight larger jet and it made a huge differance in acceleration. What size sprocket did you go with? I went with a 47 and it helped alot dont go with any bigger or you sacrafice top speed. Have Fun riding message me with any other questions.
