It did what it was supposed to but it wasnt for me. I felt it took a lot of the overrev out of the yz250x - too lean up top and didnt help with the fouling issues. Still gonna rate it good because it did exactly what it was supposed to just no #40 for me.

Works as intended. No issues.

Only use authentic Keihin jets for Keihin carbs, the knockoff jets will only leave you wondering why your machine doesn't run right.

Keihin 99101-393 Series Main Jet is a great upgrade for my CRF's BBR Big Bore kit.

much like the keihin pilot jets the only complaint I have is price. Still did the job like it should after a pipe and filter upgrade.
