I agree, that is most likely the problem. I removed the springs on mine to check the shocks when I had the bike apart, mine were good and they don't bounce. I weight about 210. Spacers would make for a stiffer suspension and possibly reduce bounce because of that. If you do decide to put in spacers, that's a good time to check the shocks, then at least you'll know where you stand.
