What do you think? What would one see from putting this on his bike?

This site says 5-7hp, but Im sure thats after a full dyno tune to reprogram the ECU to compensate for the changes.

A good port job on a single if you pull it off and put it back on is about $300 in Colorado.

All of my riding buddy's at home in Colorado are hard core racing quad/ sand dune people. A good port job is night and day. With riders of the same weight on 06 YZF-450's a "good" port and pipe will walk away from a good cam, pipe, and a mildly decked head.

If the shop is reputable for performance work and you can steal it for $150-250 your getting a great deal especially for a four.
