This Mikuni outlet adapter sleeve is for increasing the spigot diameter from 43mm to 52mm on Mikuni VM36, VM38 Roundslides, TM36-2 and TM38-86 Non Pump type Flatslides.
This adapter sleeve has been designed and manufactured for a good interference fit over the Mikuni 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 pressing on the sleeve we recommend the use of a high strength 620 Loctite retaining compound or if a not so tight interference fit use Loctite 660 or a high strength two pack epoxy. 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.
