I've done a search, but having trouble locating the actual list of the Dave's Mods. Trying to get my bud's '07 650L to run better (especially on the low end). Any help would be appreciated. We also need help with the rear spring rebound setting (we have installed a heavier Eibach spring - my bud is 7' tall and about 265 lbs.) and with air pressure setting for the forks. We ride a lot of tight trails so suspension and bottom end are critical.
