Gear noise is one of the major drawbacks of using a geartrain to drive cams. In order to minimise this, Honda used a spring mounted scissor gear system (essentially two gears slightly offset) on the gear mounted on each camshaft, as well as the lowest mounted gear in each head (driven by the crankshaft), offsetting the teeth by roughly half of the pitch. This allowed the lash to be entirely taken up by the tension of the two teeth resting on the gear below, hence eliminating some of the noise and lash inherent in this type of system. The motor still makes a whirring noise which can be heard, as this is an intrinsic property of the straight cut type of gears which were used. The gear driven cams went on to be a key feature Honda used in their line of VFR750 motorcycles throughout the remainder of the 80's and throughout the 90's.
