Anyone know what is a healthy oil pressure figure for an R1 at idle?
- and what's a normal reading when you've got you're toe down?

I've found sound figures but just want to make sure as it seems quite low:
Idle - should be not far above 7psi?
and then above 30psi at about 3000 revs but no idea what it should be at higher revs?

Can anyone help?

Hi Ali,

I researched the same question a few weeks ago after having installed an oil pressure gauge on my 2003 R1 lump- one of the service manuals I found say 6.0PSI at idle (~1K RPM) and 60PSI at 6K RPM and up (pressure relieved above this RPM).

My 2003 is dead nuts on these numbers with the engine at full operating temp. The fully cold reading at idle is usually quite a bit higher - about 50 to 60PSI (depending on ambient temps before the car idles down during warm-up), slowly creeping from ~30PSI or so from when the wax pot melts and the cold idle mode is finished settling at 6.0PSI at idle when fully warmed. Going from full throttle to fully off throttle I see dips as low as 5.0PSI instantaneously, but this may be partially gauge overshoot. I set my warning light at 4.5PSI or 5.0PSI (can't recall right now) and it never comes on. I'm using Redline synthetic by the way.

Cheers,

Aric

Does this mean your engine is running?????

? There wouldn't be any oil pressure if not...

I think Tomf may have been getting a little excited thinking your busa engined monte was running without realising you're also the lucky sonofa who has an R1 engined mini aswell!

Thats very much Aric that's spot on.
- I've only got the standard oil level sensor wired up to a light at the minute - but I have got an oil temp and pressure gauge to keep an eye on things for the time being

- I think Tomf is excited that my engine is running - it isn't,yet. it's wired and turns over, but i need to bleed the clutch to get it in neutral, then I'm gonna turn the key!

I wish - though I'll be able to work on it every evening during the week and every day on teh weekend starting June 12 when the wife and kiddies go to Greece for the summer
