This Mikuni outlet adapter sleeve is for increasing the spigot diameter to 44mm on Mikuni RS 34 carburetors with a 16mm extension so as to match the OEM DOHC CB 1979-1983 stock carburetor length.
This adapter sleeve comes with an anodized finish and has been designed and manufactured for a good interference fit over the Mikuni RS34 carburetor spigot.
This spigot must be installed by a competent person. It is recommended to carefully remove with a fine file any protruding castings found on some carburetor spigots before pressing on the new sleeve. When tapping on the sleeve with a nylon hammer, we recommend the use of a high strength 620 Loctite retaining compound and primer. The adhesive besides helping bond both items together will fill and seal any imperfections found on some carburetor spigots and also acts a a slight lubricant for the fitment.
