Why isn't it posted as a stickie in the performance mod section about how truly worthless the stock '07 and newer WR450 forks are? The base valve in these forks is totally untunable in stock form and riding the bike with the stock fork is akin to riding a hobby horse. When those 'poppet valve' springs compress off of the piston seat, there is no more compression damping and the fork is essentially a spring for the remainder of it's travel in the compression stroke. I recently modified the base valve by removing the poppet valve spring assembly and adding a conventional shim stack in it's place. The results were amazing! I now have a totally different and predictable handling bike. This should not be a cryptic mod, I would like to see the WR community better informed about the shortcomings of this fork.
