the KW crank adapter was designed for use with the stock crank pulley.
we are not familiar with aftermarket pulley designs so we cant really comment whether they will work with our pulley adapter. however, because we are using a cogged belt a certain amount of pulley misalignment/offset will be acceptable (ie the offesets of the machined aluminum faces on the pulley become less critical. there bigger concern would be whether the aluminum pulley allows the KW adpater to be hubcentrically centered per KW design.
generally we steer away from using any non-dampened aluminum crank pulley on the sheer basis that it does not have enough mass to dampen harmonics in the rotating assembly. furthermore, the change in material and diameter does not make a significant change to the the moment of inertia. our experience has shown us that a proper crank damper dampens harmonics, smooths out the engine, and increases power; aluminum crank pulleys are NOT dampers.
If your goal is to improve the throttle response and how quickly the engine revs up and down, then you need to look at the rotating assembly as a whole and start with areas with the highest moment of inertia (ie flywheel, clutch, crank&rods)
so back to the subject of aluminum crank pulley with KW crank adapter, i think the easy answer would be:
not recommend, use at your own risk.
