I raised both my 600 and 1000 by an inch, design for both was identical from what I can remember.
Here's the measurements I obtained for the 1000 as I was going to make some, ended up getting some seconds in the end for a good price.
It's not exactlty linear, and a few thousandths error shouldn't hurt.
There's that much slop in the bolts size to hole size already.
it doesn't require much precision.
Here's some figures based on several postings of measurements
made to raise and lower FZ1's.
The centre to centre distance between the bolt holes and the resulting
change in height.
137mm = 22.5mm
138mm = 17.4mm
139mm = 12.6mm
140mm = 8.1mm
141mm = 3.8mm
142mm = -0.2mm
143mm = -3.9mm
144mm = -7.3mm
145mm = -10.5
146mm = -13.5
147mm = -16.1
148mm = -18.5
149mm = -20.6
150mm = -22.5
151mm = -24.1
152mm = -25.4
