There is another thread about the FZ1 bar swap. Seems most just slice the "tit" us you put it off. Look at fz1 bar thread around post #47.Did y'all have to tap/drill the Woodcraft bars to mimic these holes? I think they're there as a "stopper," which a plastic "tit" fits in to prevent rotation of the horn/blinker and killswitch/starter assemblies.
