Frequently Asked Questions
The low speed (pilot) jet controls the fuel-air mixture at idle and during low throttle operation. It affects cold starting, idle quality, and throttle response off idle.
Signs include: poor idle quality, difficulty starting, hesitation off idle, or running too rich/lean at low RPMs. Jetting changes are often needed when modifying air intake, exhaust, or altitude changes.
The suffix typically indicates the orifice size in hundredths of a millimeter. '85' likely refers to an 0.85mm jet opening.
Typically no - most low speed jets require carburetor removal and partial disassembly to access. Some applications may allow access without full removal, but this is rare.
Consult your carburetor manual, the original equipment specification, or jetting charts for your specific engine modification level. Start with OEM size and adjust based on running characteristics.
