gs550B oil pressure light comes on if I try accelerating past 80kph?

[Guest]

G'day everyone,

as the tittle says I've noticed when accelerating past 80kph my engine oil pressure light comes on soon as I back it off and drop back around 80kph light goes away, I've suss'd it out a bit and ridden around town all day stay 80kph no probs soon as I poke it above 80kph lights on.

Any thought on what the issue could be thanks Chris

Not enough oil. Fill'er up.

(If you have just recently, you're losing oil somewhere).

Oil glass is full, on leaks just fitted full gasket kit after pulling down to fix base gasket leak

Sump screen/strainer cleaned?
Oil filter we can assume to be changed?

How much oil refilled after reassembly?

Sight glass confirmed to be gunk-free?

The only other thing I could think of would be a worn out oil pump, or a gasket blocking a passage. There have been minute differences between models I've been told, which makes it easy to install a wrong gasket.
