I carelessly rolled over my 2004 TRX500 4×4. As soon as it landed on its side it stayed running but an annoying ticking/ rattling started. It never stopped running and no noticeable damage was done. The rattle coincides with the rpm. It sounded like a valvle so I adjusted them to the recommended gap. But there was no change. Before the roll over this rattle did not exist. Has anyone ever experienced this after a jolt to the engine… roll over etc. Thanks for help.
