i was at a buddy's and got ready to leave, started the bike and realized i forgot my jacket, so i walked over to get it and heard a crash, turned around and my 'bolt was on the ground (left side), it cut off after about 3 seconds everything appeared fine, only bent the clutch lever and crushed my grip end, BUT on the ride home the oil light came on which i thought was strange cause i just checked the oil earlier that day, so i ignored it (bad move, i know) till i started hearing "noise" from the engine. it appears i'm now not getting oil to the engine, what would cause this after a fall? i'm totally stumped. any help greatly appreciated.
