definite getting to top of engine as that's where the mechanical gauge is.
don't know when relief valve opens at. its a new pump but yeah 5 bar is when i turned it off, maybe when the engines running that sort of
pressure will open the valve, and when oil warm up it should settle down to 3 bar (45 psi) at 2000rpm

Is it a new oil pump, because isn't the relief valve built into to it ?
The specified figure for the afh/aee oil pump is 300kpa at 3000rpm (or in laymans terms 43.5spi when you rev it)
but this is with warm oil (80c)
Cold oil I would expect more, but not at the low revs off the starter.

yeah, its a brand new pump.
i didn't allow it to settle down. i just thought, cool, im getting pressure, 2 bar, then 3, 4, 5 in quick time, then switch it off. maybe it
needed another second or so to burst open the valve,
yeah i believe the valve is built in the pump it self. a little ball bearing with a spring

say starter motor is turning the crank at 200rpm.
is that too slow for rings to get damaged?
if that is the case then ill be doing starter motor way for sure.

The rings of an engine are not under much pressure with the plugs out, even with plugs in unless the engine fires the loan is minimal. Ifworried (and
it speeds up cranking) put a drop of oil down the bores

I did what you and other lads said and it worked. got oil pressure. so from no oil pressure i now might have high oil pressure lol
Is it ecpected to have high pressure such as 5-6 bar with a new build on starter motor

Thats about 80psi, does seem high.
Have you got remote oil filter or oil cooler? if so remove and fit filter back on the engine

just a normal cylinder shape filter which screws on front of block
i didnt allow anything to settle. soon as i saw pressure going up and up and up i turned it off.
don't want no galleys plugs to blow out of engine

Of course not, better have that happen on the road so unsuspecting motorcyclists can have a good skid. 
Seriously, this needs looking at, if indeed there is a problem. I updated pressure range in previous post a D it does seem to be high.
Regardless of engine temperature, the oil pressure relief valve limits how high pressure can go.
With a worn engine, oil pressure will drop when warm as it is not high enough for the valve to open.
Question is: do you trust the pressure gauge?

i dont mess with motorcyclists lol,
do i trust the pressure gauge. I trust it to be no worse than 1 bar off the true reading either way.
it's not relief valve as pump is brand new.

If you think because it’s new it’s not faulty then I think you should wake up

well i got it running up to 2000rpm then switched it off after 3 seconds.
noticed there was fumes in the garage almost instantly on starting, greyish, dark. stunk of oil.
i was more concerned with the noise. there was no mechanical knocks or screeches.
just felt like a loud engine and very deep sound. i think the loudness was the garage.
but felt deep.
if the vr sensor on megajolt is not telling the right firing points this can affect timing.
on the megajolt software if the rpm matches whats on the car dashboard rpm dial then this means the vr sensor is accurate?
