John,
When you land short on these jumps, are you coming down flat, or possibly rear-wheel first?
Also, in my book there is a difference between "harsh" and "stiff". Your forks might be stiff during break-in, but that feeling should really go away after a short time. The suggestion about making sure everything is lined up correctly is also important. If your forks are binding because of improper set up, that could be a big part of the problem.
How is the bike in the turns? How does it feel on braking or accelleration bumps?Do you consider it to be harsh in those situations, also?
