38mm CarbFrom $1
Table of contentsNo headersThe KDX top end is originally designed for a 35mm carb, since we want top end grunt we went for a Keihin 38mm PWK Air Striker Carb. This has so far worked out really well with better low down performance than the 28mm (an older KDX carb which we had fitted for running in). This overall performance is probably helped by a longer manifold (to make it fit) helping the bottom end performance. The "air striker" feature is also designed to aid low down air/fuel mixture.
A = 46mm, B = 63mm, C = 91mm, D=171.6mm (from Keihin website) One issue that had to be resolved was throttle travel not allowing full throttle, as we now have a carb with a 14mm larger throat that the original PX. This was resolved by trimming back the throttle stop, so the cable travels further. Another moditifcation is an angled top cable entry point. With the original (below), the cable will hit the side panel.
