I have a 2013 gsxr 750 w/ 14k miles, manual cct and aftermarket header. Lately I've noticed a ticking, that has been getting worse over time. It used to just tick at idle, once i took off it went away. Now it still tick as i pull off up until 5k, after that i can't hear it over the intake noise. I've also noticed that once I let off throttle to engine brake it goes away and starts again when on throttle. That's the part that get me, why does it go away off throttle? Valve lash, adjust cct?
Thanks in advance,
Edit, the reason I mentioned header was I've heard you can hear valves more with aftermarket headers. Also the ecu had a crazy tune (advanced timing 12 degrees) and I've hear it detonate a few times before I had the ecu reflashed 8k miles ago or so.
