2009 Honda CRF100F Torque Specs
Shop parts for a 2009 Honda CRF100F Dirt Bike.
The 2009 Honda CRF100F was a continued expression of Honda’s commitment to an accessible, reliable trail bike for entry-level and recreational riders. The air-cooled 99cc four-stroke single kept its same fundamental architecture—electric start, low seat height, and predictable power delivery well-suited to developing riding skills. Torque specifications for the ’09 CRF100F are the baseline for all routine service procedures.
Engine & Oil System Fasteners
Valve clearance checks are a periodic service requirement on the CRF100F that the CR two-strokes don’t share. When the valve cover is removed for clearance inspection, the cover bolts must be returned to the correct torque to prevent oil weeping from the gasket. Similarly, the oil drain plug torque is the most frequently performed fastener service on this four-stroke machine.
| Fastener | Torque (ft-lb) | Torque (Nm) |
|---|---|---|
| Spark plug | 11–14 | 15–19 |
| Cylinder head bolts | 14–16 | 19–22 |
| Valve cover bolts | 7–9 | 10–12 |
| Oil drain plug | 18–22 | 25–30 |
| Flywheel nut | 29–36 | 39–49 |
