Mikuni RS 36mm Carb Kit- Honda DOHC CB1100, Honda CB900, Honda CB750

This Mikuni RS36 carburetor Kit is more suited for the Honda DOHC CB1100 but will be compatible for both 750’s and 900’s with worked engines. They will breathe a whole new lease of life into your machine with an up to 25% increase in power, whilst making it perform and operate as it should with no hesitations or flat spots.

You will very quickly realize that the expense of a rebuild of your old worn OEM carbs can far exceed the cost of these new units and unfortunately as with many rebuilds now days you only have the option in many cases of gambling with very poor quality aftermarket parts. Considering this and if intending to ride and enjoy your motorcycle it makes good sense to retire your OEM carbs into the cupboard and step up to a set of RS’s.

Before rushing in and ordering please firstly check your carb spacing and carbie sizes for compatibility. These are not suited for downdraft engines.

This Mikuni kit comes in two fitment options– with the following carb centre to centre spacing’s for direct fitment to Honda CB750. CB900 and CB1100 and will adapt to the stock air-box (55mm dia.) and engine inlet rubbers.
