Hi does anybody have any experience with Fab-tech revalve kits, or know of any other options availible for the WP 43mm forks the seem to beat me to death on brake stutter bumps and chop?
A base valve kit or a "shim kit" won't resolve the harsh action that you are experiencing with the 43mm WP and the original base valves are fine. The cartridge needs "more" to "fix it".
I would recommend that you go to LT-Racing for this work - or at least call him to get his advice. He is very reasonably priced and doesn't charge any extra for the additional work required to resolve the issues with this fork. www.lt-racing.com
