Honda CB450/CB500T Mikuni VM32 32mm Carburetor Kit

Retains the factory side panels for a classy, original look with all the benefits of Mikuni VM carburetors.

Breathe new life into your Honda CB450 twin with this high-performance Mikuni carburetor conversion kit. You can toss those leaky old Kehins, because this kit offers quicker starts, rapid throttle response and a better top end utilizing the legendary Mikuni VM32 – the choice of racers and custom bike builders worldwide.

This is the only conversion kit currently available utilizing billet, CNC-machined manifolds specifically designed for the CB450. The stock manifolds on the CB have always been a problem. The rubber breaks down and cracks, causing air leaks, leading to a lean condition that can rapidly destroy your engine. Some folks try to use CB350 manifolds for their conversions but they just won’t work. Not only are they the wrong size, they create numerous clearance problems with the petcocks, cross over tube and side panels. Our beautiful billet aluminum manifolds solve all these problems. When mated with the VM32 and our heavy-duty rubber adapters, this kit will provide years of dependable, trouble-free service.

This kit will fit Honda CB450 K1 models (1968-74) and CB500T models 1975-76.
