front suspension
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.lrutt wrote:I don't think the problem is spring rate, it's total lack of dampening. At least on mine. You can make is stiff as hell but it will still bounce without any dampening.

The spacer modification does not give you modern suspension, but it did help me win the AMA Mid-Ohio Vintage MotoX this year (my age class) on a 1963 Dream......
