The 16 SHA works fine. Kitted bikes set up for more RPM range do better with PHBG because you don't end up too lean at WOT and too rich at idle. The SHA is adjustable however. Using micro drills on the lowest idle orifice in the carb body and or carefully drilling the mid tube orifice can expand their usefulness. If you overdrill, patch with JB Weld and re-drill. Keeping the carb stock though and living with it's minor limitations on a not too hot set up is a joy of it's own
