I wish I knew I've looked at so many articles and forums but since the Wolverine was the only sub 500 I looked at somewhere I saw a mentioning of a 500cc kit for a little over a grand. Unless they were wrong and it was only a 449. So the pipe, filter and jet kit make a big diffference? any mid throttle response issues? I've only driven a few things jetted a cbr600 and a yamaha jetski and both where jetted to the max and mid throttle was almost non existant as they were setup mostly for racing.

 

No with the jet kit, jetted just for the pipe and high flow filter I have no mid throttle issues at all. I have great power throughout the range.
