I have a 250X with a power core 4 and a K&N Airfilter. I was wondering what jet kit in need. And also what is the best jet kit for my 250X. Thanks for you help!!!!!!!!!!

 

If you were smart you would NOT waste your money on a jet kit ! just gat a $2 128 , 130 ,and a 126 sive jet and see whuch one works best and move the clip up one notch on the needle. thats what I did to my X and it runs good.
