Anyone having trouble with the performance of the torsion throttle springs should be sure they have complied with SB 18-03-06 Rev. 1, which references SB-00026 which details installing VA-00276, Throttle Spring Retainers.
The retainers not being installed, has an influence on the rotational friction of the spring which can effect carb synchronization.
