Since it's warmed up aroundd here, my Eldo's been losing oil presssure when fully hot. It goes right up to pop-off pressure of 60 psi when cold but slowly drops as the oil heats up to 37 psi at 80 mph on the freeway, when fully hot. That doesn't seem like a safe pressure to me. Any opinions on this, given that I need to ride it to the National in two weeks, through some ferly hot country? Stuck one of those thermometer dipsticks in there today, and it hit 105 C after less than 10 miles on the freeway. That seems kinda high, so I'm wondering if the crux of the problem is excessive oil temp, rather than excessive clearance in one of my bearings. Everytime I've seen heat problems before, they were caused by excessive blow-by and consequent oil puking out the breather. This Eldo does not drip or puke oil out the breather, even after extended runs of 85-90 mph, so I can't believe it's blowby. Anyone have any ideas? Running 20-50 AMSOIL. Now, I put the extended sump from my LeMans on there and hope to get out for a ride in an hour or so to see if that makes any difference. I also changed out the pop-off valve for a known good one.

Now dod-dern-it-all Greg, now that I've put a couple thousand miles on
the Eldo and have just started to get the feeling like it's a solid,
unbreakable, tough machine, here comes you with these horror stories of
broken sidestands and low oil pressure - these sound like the stuff of
Centauro legend, or a 60's Royal Enfield 750 twin, not this solid
steel-and-alloy Italian steed I've got sitting in the shop waiting to
ride with me tomorrow.
NOW I'm anticipating cracked fork stanchions, warped rotors, clogged
fuel injectors, and a zapped engine control computer....well, some of
that, anyway.
Makes me glad I don't have an oil pressure gauge on mine.....Just for
info, the highest pressure my BSA runs on its plain timing-side crank
bushing, hot, at highway RPMS, is 20 psi. I'd kill for 37, but don't
know what would be right for an Eldo.
Good luck with yours, though.
