If there is an issue with the float valves in the carb, gas can get into the oil and thin it out.

That's one possibility.

The other possibility would be a bad connection on the oil pressure sending unit. Carefully remove the wire and make sure the connector is clean and snug.

For you, it looks like the sending unit is going to be on the right side of the engine, towards the bottom near the front. It's screwed into the case and has a wire attached to it.

5W-40 oil is fine, as is 87 octane, for the Ninja.

Make sure it's idling at 1300 when fully warm.
Oil level is.. pretty high. it fills up the sight glass if I keep the bike upright and look. 800km in this season so far and first time it happened though.. should I try draining it out a bit? I messed up when I changed oil before winter and went over the ideal amount a bit..

I'll give it a sniff later for oil smell, if carb issue.. I guess I'll have to crack it open sooner than planned. I was going to do the pilot jet swap to 40 instead of stock 38 anyway

thanks guys! I'll keep checking to see if symptom continues
