Tappet/valve noise needs periodic adjustment
The air-cooled LS410 develops audible tappet noise and benefits from periodic valve-clearance checks; neglect leads to rough running.
Watch for: Ticking from the head that worsens when hot, rough idle, dropping fuel economy
Do this: Have valve clearances checked every 10,000 km and keep to the oil-change interval.
Typical cost: ₹500–₹2,500
