I recently got an 07 zx10r and I love it. About 4 days ago near the end of my ride which is about a 20 minute ride on the highway at speeds that fluctuate between 70mph to 120mph I began to get a red blinking light and the FI began to flash. There was no loss of power and it made it home no problem. The next day I was on my way home again when this time the red light started blinking but this time the oil symbol was flashing instead of the FI. Again it made it home just fine. I checked the oil level and it was a bit high but nothing that would warrant concern. I looked at the owner's manual and if said that particular light comes on when oil pressure is dangerously low. The next day I was headed to work when towards the end of my ride the bike dies out of nowhere with the oil ajd red light flashing. I turned the bike off and back on and tried to start it and it started back up. That seemed to be how it was until today when I noticed that there was a bolt missing from the right side casing. The middle casing bolt. It was leaking s little oil but not pouring out. I replaced the bolt but I fear I have screwed up my engine by riding it with the oil issue. I now get a knocking noice that I can not only hear but feel in the engine. I'm not sure if its the lifter or the rod. No loss in performance but I didn't ride it far. There seems to be a bit of oil seepage around alot of the gaskets but nothing that I would consider excessive or make me think that a gasket had blown. Just wondering what peoples thoughts were on the issue. I will fix it but would prefer not to go into the bottom casing. Thank you.
