This is a part that we made for ourselves but now we sell it as a standard tool. Kawasaki KZ900 and KZ1000 cylinder heads often strip out the bolt holes which hold the cam cap in place. This fixture positively locates on the cap cap dowels and two aligned drill bushings guide a 1/4" drill bit perfectly down the bolt hole. From there you can tap and install a heli-coil or a time sert.
