Hi everyone - got a weird problem and my dealer seems to struggle
Oil pressure on idle when warm is approx. 15psi which when I rev up goes up to 60psi. As a result the dreaded red oil warning light comes on when it goes back to idle. This goes away when I speed up or when I ride but this comes back on as soon as I stop at a red light. Been told that pressures are within spec when rev'd up or during a ride but not at idle. Dealer does not necessary believe it is the oil pump since pressure goes up to within spec when riding. Been told it could be the caskets at/behind the oil pump (best case), the oil pump or even the caskets deeper within the engine (worst case) as this requires an engine re-build. Costs estimated anywhere between C$1,000 to $2,000 for a 6 year old N8VGT with only 39,600 kms (25k miles)

Thoughts from the specialists would be welcome - thanks

As I said here https://www.guzzitech.com/forums/th...e-sensor-again-on-norge-8v.20664/#post-163396 I think one of your sump gaskets has a small leak at an oil port. The two gaskets (sump and extension) are fairly easy to replace. Just make sure you remove all sump bolts (I believe there are 14) as some are kinda hidden. I can't recommend any gasket treatment. I doubt you have an oil pump or oil pump gasket problem.
 
These symptoms are the exact same as mine. However, now that the weather is cooler the light does not come on anymore.
Man do air cooled bikes ever run nicely in cooler weather. Mine seems to thrive at 15 C.

Thanks - how much time/effort is it to replace those gaskets?
 
Well, turned out it was the gaskets as predicted by so many of you. One gasket had failed (corner ripped) and the second was about to. Of course, no gaskets at my dealer so had to wait until they arrived (from Italy or NYC) and once exchanged all good again. Managed one more glorious fall ride yesterday and bike was back to normal. Just clocked 40k so hopefully no more issues for another 40k or so
Thank you all for your comments and advice.
