I'm thinking to check the things that control the timing of the upshifts,

Does
delay mean that the 3-4 shift is
initiated at a road speed that is higher than you feel is correct?
OR
Does
delay mean that the shift is
completed in a slow, sloppy, or flareing manner?
By your further comments, it would seem that the first instance is the case. If that is so, look to the balance between the throttle pressure (control/Bowden cable) and the governor pressure. Either high throttle pressure or low governor pressure will cause a shift to be initiated late.
Accumulators and their springs are not involved in shift
timing, but do affect shift
quality.
