Yes it will increase oil pressure but by not much at all
I did a thread on oil pump upgrade with. More details

I stydied your oil pump thread and want to increase my pressure too. What spring pressure and oil pressure did you end up in the end? Your first upgraded spring didn't give you oil pressure that you wanted. I have 3 progressively stronger springs just waiting.

It's stil the same Spring but I will increase it 20% next time I open the engine it's the old cases so requires case split.
It's also the old head which has oil feed to everything And I added a lot of oil flow to the main Bearing on the lhs so you probably don't need as strong a spring as me.
I'm Travelling at the moment so don't have good internet

Cheers Bush, it looked like a bodge to me so I fitted a standard spring. Can't imagine it's a JBS upgrade!!
Do you think it did actually increase oil pressure!?!?
Yes, I read your thread on the pump upgrade, interesting stuff!!

This pump is some kind of upgrade?
The peg locating hole in the shaft is nearly flush with the cap. To locate the pump gear the previous builder has ground off part of the cog face.
The pump cap is located with Allen heads, well and truly rounded off, no idea how I'm going to undo them! Probably cut a slot!

Hi Spanner,
Which KTM did you use? Straight fit?
Did either increase pressure significantly?
Do you use the standard relief spring?

77038011000 is 15mm wide, I think the JBS was 14mm?
so I surface ground it down to suite the JBS cover.
The JBS cover was causing some binding and I had to move the
hole the shaft goes through to stop that. Yours may be OK.
I added a 3mm packer as Bushie suggests to increase the oil
pressure. I do not have a gauge fitted so can`t give any figures
for the pressure.
I did a bit of work to the inlet and outlet ports with a 1/8 ball burr
and a pencil grinder to help the flow. A steady hand is required.

OK, I borrowed a gauge, oil heating 0-300psi, a bit heavy duty but needs must. Tapped it into a spare cover, 1/8 bsp.
Around 15psi on fire up around 1800rpm, bring the revs up 3000rpm+ around 35psi...all good?
Left it ticking over until she was good and hot and the pressure drops, 10psi tickover and 25-ish with a blip. That would be due to hot thin oil?
Am I being a bit paranoid?
