Shock Settings

New FZ10 has about 500 miles on it now and I have been slightly confused about the rear shock. Having read other posters concerns about fine tuning the settings I figured I'd give it a shot. I weigh 147 lbs with gear so the spring should be OK. I noticed right away that the compression adjusters don't make much difference at all and the rebound adjuster is overly sensitive with either not enough rebound which gives the rocking horse pogo effect or to stiff with horrible ride on the freeway. I ride fairly aggressive running the tires all the way to the edge and I'm close to perfection but not quite there yet. I hate when obsession kicks in, as I keep all the necessary tools for the adjusters with me at all times..
