So I don't know if this is a recent issue or if it has been going on for sometime now and I just haven't heard it cause I was listening to music. However I noticed when my bike is at idle there is a ticking noise. I have read some of the other threads but all the noises I have read sounded like knocking or rattling . This is just a persistent tick that goes up with the reves . At a certain point you can not hear the tick due to the exhaust covering it up. Is it time to get my valves adjusted , I had a few guys from Philly sport bike meets tell me it may be a valve tap. My bike just hit 13000 miles not too long ago and oil was done 3000 miles ago with synthetic . Any feed bad would be much appreciated.
