Megadan, remember that Keihin carbs are described by the diameter of the air cleaner side while Mikuni's are described by the venturi diameter. a VM 28 is equivalent to a 32 mm Keihin. However, the Keihin shown in the link has a starting jet instead of a choke which should give improved performance above 3/4 throttle even with the 30mm model...ARH
