76 r90/6, 28K miles.
took the bike out over the weekend for a 250 mile ride from queens, ny down to manahawkin, nj. a lot of highway riding @ 70-75mph. very humid all day, rode through two short rain storms, and floating around 80-90 degrees all day long. oil change was done about 750 miles ago. checked oil level before leaving for the trip and it was close to the 2L mark. bike has never had any issues with the oil light / oil pressure in the 2+ years i've owned it, it only comes on when i turn the key from off along with all the other idiot lights.
upon returning from 249 of those miles, on the 1 mile back to the garage while coming to a stop at a light, the amber oil light came on. when i came to a stop the light remained lit. taking off from the light over ~1300RPM the light flickered, then went out. the light came back on at the next stop light. same thing happened after taking off, shifted into second and revved the bike and the light goes out. when i got back to the garage and let the bike return to idle the light came back on. after getting off an inspecting, i didn't see any significant leaks or smoke coming from the bike, the motor was noticeably warm. i did not check the oil while the motor was hot, it was 11:30PM and i was ready for bed at this point.
also just want to point out from other threads i've checked this is indeed the amber oil light and not the red generator light.
came back the next day and checked the dipstick, the oil mark is maybe the slightest touch lower, but is pretty close to the full mark. no evidence on the ground of any oil leaks. visual inspection around the bike looks okay.
where to start with diagnosing this? is running the motorcycle at all dangerous at this point even just to see if the light goes out?
