Genuine Mikuni diaphragm(s) and o-ring. H.S.I. assembled "basic" rebuild kit for SBN carburetors kit compromised of the main internal parts that seasonally wear out in the carburetors.
Whether it's been used and had a bunch of fuel ran through it, or sat since last year and had the same fuel sitting in it, these diaphragms and o-rings go "bad" and need replaced to keep the carbs running with no headache. We recommend to replace the remainder of the internal parts with a full rebuild kit every few seasons.
*Services ONE carb. (Non I Body).
Included parts are located on the diagram: #1, #2, #5a, #10 and #16
At H.S.I. we do note mess around with any aftermarket carburetor internal parts. We recommend using ONLY genuine OEM Mikuni parts, do not settle for less. Buy once, cry once.
