Actually you don't have to remove the carbs to do the needles. Take off the tops, pull all the bolts out of the slide lifters and the throttle, remove the rubber plugs and the tab that locates the throttle shaft, and you can slide the throttle shaft to the right to free the left 2 slides, and back through to the left to free the right side 2 slides. Don't push the shaft all the way out of the throttle connection...it's a pain to put it back in without removing the return spring.
