A common occurrence with these giant ZTL rotors when replacing with new EBC HH pads. The noise you described is pad-rotor-caliper related. A discernible "clunk" in the front end after performing the work you described is always faulty wheel bearings or steering neck bearings.
If you hadn't during your work, check and perform the following to alleviate the noise:
1-Caliper pistons not fully retracting. If suspected, will walk you thru proper procedure to address this.
2-Pads not fully bedded in to new rotor. Go to EBC website or google "EBC motorcycle brake pad bed-in procedure". Their site has simple explicit instructions to perform same.
3-Rotor "square washers"...rotor bushings....rotor attachment bolts worn beyond specs. Extremely unusual but check all.
4-Rotor failing to "float". Check rotor pressure springs and locator holes in rim. Holes must be pristine and springs must measure within spec length.
5-Rotor manufacturing defect re lateral run-out. Lift front...remove caliper...spin and check rotor laterally.
6-Caliper pad slider pins severely worn OR not lubed prior to installation of new pads causing pads to bind up on the pins.
7-Check the rotor bushing holes which are stamped into the rotor during the manufacturing process. If just a tad too tight, the rotor won't float. If so, gently massage each hole with appropriate file or dremel tool. Be gentle and deliberate if doing this.
NOTE: When I perform this work I always put a very LIGHT coating of brake caliper/brake parts lube on the caliper pad pins and the lateral surface of each rotor bushing. Helps immensely.
Good luck.
