Use plenty of good silicone around grommet + wires and i think your problem should be sorted.

The design of the KZ900/KZ1000 tanks differ from the Z1 tanks in a couple of ways. The welded seam underneath the tank is to the inside of the petcock mount, and the fuel cap mount only accepts the locking gas cap. This tank will fit perfectly on the Z1 (1973-1975), but you must use the locking gas ...

Bore size is 5/8th

They do good wheel + shock rebuilding.

Z900 frames do not have fittings for rear master cylinder.

Z1 type inner mudguard will not fit Z900 or Z1000
