Cam Chain Tensioners:
The cam chain tensioners can also wear over time, requiring replacement. Similar to the primary tensioner, an upgrade is often recommended.
Exhaust Flange Leaks:
Exhaust header flange leaks can occur due to heat cycles and vibration, often requiring re-tightening or replacement of gaskets.
