§ 02 / About this part
What it is
The BOYESEN REED PETAL FIBERGLASS, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.
These fibreglass petals sit within the intake block to control the fuel-air mixture entering the crankcase. Over time, the edges fray or the material loses its tension, leading to a boggy bottom-end and poor starting. Inspect these during every top-end service for any signs of chipping or gaps. Fresh petals restore crisp throttle response and improve scavenging efficiency. They are a simple but critical component for maintaining 2-stroke performance. Ensure the seating surface is clean before bolting the new petals into place.
