Whether replacing worn out OEM manifolds or adapting new carburetors to your project, using genuine Mikuni manifolds ensures a tight leak free fit and years of durability.  They're constructed of a rubber polymer that remains pliable in cold weather and after many years of use.  A high UV resistance means they won't crack or deteriorate in sunny climates.  

These Mikuni rubber holders are modified by us to specifically for the wider mounting bolt pattern on older Honda CB350's and CB450's.  They fit perfectly and will work with all Mikuni VM30, VM32, and VM34 carburetors.  They are sold as a kit, you get two rubber holders for a complete job.  Can also be purchased individually, please inquire.
