I have exactly the same problem. Is this common with Z1's?

I have often had them welded.
Can't remember if they had a 8mm helicoil in them as standard.. check!
It is common problem for these Z1 fork legs to crack and break-out at these front mudguard attachment points, as this guard acts as a fork brace.
If you have ever riden a Z without a guard you would know. Even a plastic guard is not strong enough to tie these fork-legs together.

BEWARE - there is a possibilty the alloy leg may distort - then be useless

Big K modified them early on from the early 72 Z1 type due to this weak defect.
Obviously they were still a slightly less weaker area.
