'84-'85 VF500C Magna V-Four KeiHin VD58 and VB59
VF500C are very different VD carbs than most VF models. They only share a few parts with VF500F Interceptor and VT250F Interceptor. These carbs can be a challenge to build properly and great care should be taken before servicing.
Below is a set of '85 (VD58CA) carbs. Both VF500C models look the same, but do not share the same internal tuning parts.
