A trick we used to use is to find a piece of pvc pipe just wide enough to fit in side the fork tube and cut it to the desired length to stiffin up the forks. This will however shorten the travel of the springs. Also make sure that you smooth out the edges of the pipe. The best way though is to buy stiffer springs.
