82 KZ1100 spectre - where to screw in an oil pressure gauge

Hi All. I can't seem to locate where on this engine I screw in an oil pressure gauge to test oil pressure? What should the pressure be? 

Kawasaki manual doesn't seem to show this access position or define a spectre engine model specifically. Is it a KZ A, B, or what engine?

Thanks. 

Greg

81-84 KZ1100 Shaft FSM (99924-1032-03) has engine oil pressure information on page 1-9 at the bottom.

See 92066 (92066-021) in part list and diagrams below for oil pressure test location.  Note o-ring 670A (670B2015) which is located behind the plug.

Main oil gallery accessed via the m14 plug next to the ignition cover.
These engines run high volume , low pressure so only expect to see around 3psi. 

The 1100 Spectre (D1) uses the same engine as the 1100 shaft drive (A1, 2, 3) and the the 1983 1100 LTD (L1)
The engine numbers start wit KZ10AE.........
