Cyclepedia Honda XR150L Online Service Manual

Did you know that the Honda XR150L?

• Crankcase Breather Maintenance: The stock crankcase breather on the XR150L is poorly designed, which can lead to excessive oil consumption.
• Valve Clearance Checks: The XR150L’s simple two-valve, air-cooled engine requires valve clearance inspections every 2,500 miles. Regular adjustment is important as the exhaust valve tends to wear down more rapidly over time​.
• Centrifugal Oil Filter: Unlike traditional oil filters, the XR150L uses a crankshaft-driven centrifugal filter to remove particulates. This system requires cleaning every 7,500 miles to ensure the oil remains clean​.
• Frequent Oil Changes: The XR150L has a low oil capacity of about 1.2 liters, requiring more frequent oil changes compared to larger bikes. The recommended oil change interval is every 2,500 miles​.

Regular attention to these areas helps ensure the XR150L remains reliable and performs well over time.
