No I didn’t drill anything, in fact I left the vac ports you installed in the Suzuki injector ports (only because the pitch of the port is too extreme and would fire fuel into the floor of the runner so atomization would be teh suck).
There are tiny holes in the floor of each throttle body, that appear to bypass the plate, but there is nothing that could possiblly control them…unless the secondary butterflies on the GSX-R are what modulate the flow that seeps past the primaries:squint:
