Quick question- 05 ZX6. Runs fine, no performance issues. Jardine exhaust is the only modification besides cosmetics stuff.
During idle the bike 'chirps' very softly. I can barely hear it over the engine, but it's there. Sounds like a bird... kinda... Increase revs and it goes away.
Any idea what would cause this? Sounds like it's coming from top of engine. Could it be the exhaust manifold gasket or similar ?? Should I even bother with it?
