This Mikuni outlet adapter sleeve is for reducing the spigot diameter from 40mm to 36mm, when installed using Loctite 620, on the following Mikuni carbs – TM32 and TM34 Flatslide carbs, RS34 carbs and also VM30 and VM32mm carbs. This sleeve is a loose interference fit for our VM34 and TM33 carbs where permanent fitment requires the use of Loctite 660 which can be purchased elsewhere in a 6ml tube for around $10.
This adapter sleeve is CNC machined, tapers down internally to 29.5mm and comes with an anodized finish.
This adapter 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 except where mentioned previously. 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.
