Mikuni Mounting Flange Super Short ASSY 33-28mm Tapered ID, 40mm Boot ID

Description

This Mikuni Super Short Mounting Flange has a 33-28 tapered ID, with fitment for 49mm thru 59mm stud centres.

This is the shortest version available and ideal for  applications where fitting 32mm thru 34mm carbs to cylinder heads with 28mm or smaller ports for maximum surface to surface connection and inlet funnelling down to 28mm or slightly smaller ports.

This mounting flange is designed for fitting Mikuni carburetors with a 40mm spigot outside diameter to any engine with mounting stud spacings ranging from 49mm centre to centre measurement through to 59mm. The alloy stub flange is made using 6061 grade Aluminium with a silver anodized coating. The inside hole diameter reduces down from 33mm to 28mm with a total carb set back from the motor mounting surface of 22mm. The 40mm outside spigot diameter is for matching with Mikuni VM30 thru VM34 Roundslide carbs, TM32 and TM34 Flatslide carbs. These also suit the TM33 flatslide pumper carbs plus RS34 for fitment to multi cylinder engines. The slotted mounting holes in the base do suit mounting hole centres from 49 thru 59mm when using up to 5/16″ or 8mm Button Head screws. Button head holts (not supplied) have to be used for clearance under the rubber boot. We do have some sizes available here for purchase where type the word “button head” into the main menu search box.

The assembly includes a gasket and our shortest version heavy duty rubber boot attachment sleeve which has a 40mm inside diameter both ends and comes with stainless steel hose clamps featuring rolled outer edges to protect the rubber. This rubber boot doesn’t have the usual 4mm wide spacing block separating both spigot surfaces to again minimise the carb stand off distance.
