110psi is the norm but depends on how accurate the gauge is really.

Thank you sir 👍 It's a new one so should be somewhere near😊 So really my 95 reading is a bit below par but should still run ok me thinks.

Depends on gauge calibration and how you use it. wot and kick til gage stops moving, 5-7 kicks on mine.

Compression tests are ambiguous.
Two testers will often get differing results on the same engine with the same test gear.
That said: 95 psi = rebuild time.

Glad that helps.
Personally I'd rattle can spray a frame rather than powder coat it.
Looks better with oem style paintwork and doesn't result in screwhole and fit issues either
