Hi, I have a 125, I was riding along a dual carriageway doing 75mph and all of a sudden my bike decided to drop speed. I dropped down a gear and made it to somewhere safe to stop, after the jolt my bike started randomly ticking, I got home at low speed with this ticking. I checked my oil levels and they were low. So I refilled the oil the ticking persisted and is more persistent when revving the bike. I was riding at about 10,000rpm in 5th gear when my bike jolted and the ticking began. It's loud and sounds like metal clashing off of metal and instantly jolted and speed decreased. What could be the issue?
