I don't believe there is any reason to get into where the oil filter and pressure is - you could probably just put the hole in the offset where the filter cover is if you want to yank on the guide and tensioner plunger.  That spot is not subject to the oil pressure - just the crankcase huffs and puffs of the running engine.

I still would prefer just finding a way to lock and release the pawl.  Put the larger spring in as Verslagen has suggested - then find a way to pull on the pawl to release it temporarily while you rotate the engine over a few tirmes......rather than pulling on the plunger.

I am not sure how you are going to measure that pressure......the pressure changes with each stroke of the piston.  At 1,000 rpm the piston is going up and down 17 times a second....the pressure gauge is going to bounce around with it.  The positive pressure is going to be limited to whatever is leaking past the piston as blowby, which will be quickly vented out the breather tube.  The crankcase really only has a very small amount of pressure - but a whole lot of oil spray and vapors moving around.

Not easy to see with 2 odd scaled pic's.
but the pawl is directly under the "U" in SUZUKI.
An access port in the upper left corner under the filter cover would be under the housing to the left and below the pawl.

JOG, That's what I was trying to say.
