Well, my sweet profit share bonus check is going to good use. I dropped off my '07 YZ450F's suspension off at F/C for a complete re-valve. I had a great informative conversation with their technical suspension rep. Turns out FC has quite a few trick updates that can, and will be done to increase the "plushness' of my "less than plush" '07 KYB YZ suspension. For the shock, FC has a special rate high speed compression adjuster spring, and they also have a custom modified valve plate that resides behind the HS adjuster valve as well (the stock valve is too restrictive). For the forks, FC also has a more plush upper damper rod assembly spring that they are going to update as well (not to be confused with the regular fork spring). So, about $650 later, hopefully my much loved '07 will even more loved. I like the bike thus far, but I am a tired , skinny 165lbs all geared, and the '07 suspension just has never been right for me.... i'll update this once I get some feedback laps with the modded suspension..
