For my trx250r only being .030" over, it RIPS!!! The port work Jesse did woke this bike right up!! Thanks again!

Couldn't be happier with how my Banshee cylinders turned out. It has unbelievable power. Jesse is the most helpful honest person I've ever dealt with, customer service is excellent. If you want to make power, better be getting a MacDaddy port job.
