glad you're okay buddy! I went down on my old 636 going ~85 wearing a hoodie and jeans... definitely didn't feel good! I ended up going off into woods so that helped lessen the damage that was done but definitely was pretty brutal.
With that said... is it the oil light that's on? When I got into my last accident I had the same issue, turns out air got into the oil.. I slightly bled it by loosening the oil filter a bit, starting the bike until it starts seeping out oil just a little bit, tighted it up then turned it off then back on. I'm willing to bet that happened because I've had to do that a few times before on my old zx6r
