Look at this picture below while
you chew over the statement about
the virago having over 20 rebound adjustments but only 6 are available at one time.
This could cure a to soft feeling
in the rear end.
You may not need new spring but more rebound because the spring is doing too much work.
This could be from bad factory settings or a PO that tinkered to much or pieced together bikes.
If all 6-rebound setting are to
soft go up 6 or 8 spots.
If only a few are to soft go slow.
