These intake components sit between your carburettor and the cylinder. They control the fuel-air mixture flow into the crankcase. Over time, the edges of the petals fray or chip from constant high-frequency vibration. Worn petals cause hard starting and a muddy throttle response. These fiberglass units offer a direct replacement for tired OEM parts. Check your reed block for light gaps before installation. Ensure the seating surface is clean to maintain a proper seal. Fresh petals restore the snap to your two-stroke powerband. This fitment is specific to your intake tract.
