Standard for
Fork oil 10w
If you have not gone for stiffer springs (just progressive) you may want to stick with the same.
I would try with standard firs if its too soft move up to 15w.

Agree with KwackerZ1, however, the Z1A is getting old and it is quite likely these are the original forks. hence, there may be a bit of wear here and there. I would go, first up, for 15 weight.
15 weight is not easy to get in some places. So, remember you can mix equal parts of 10 with 20 to get 15!
