I just contacted Kenz to port my cylinders. I had heard good things about them. Told him I wanted a port job. Next thing I know he is telling me I need Vforce reeds, welded crank, etc., etc.. I had to cut him off to explain that I already had all of the bolt ons installed and just wanted a port job. He replys with, "Well, bring in the motor so we can port the cylinders and tune the motor. It will run you $1,033." Frankly, he didn't seem too interested in doing the work and I am not too interested in spending my money there.
