Saber Cycle invested in the reproduction of the GL1200 carburetor slide diaphragm that is now IN STOCK . This slide diaphragm was obsoleted about 3 years ago by Honda where it was identified as the vacuum piston diaphragm, OEM 16111-ML8-741. Owners of GL1200s that need slide diaphragms replacements are getting horrible gas mileage and some GL1200s are being parked because they can’t run.
The GL1100 and GL1500 are the only Goldwing models that have accelerator pump diaphragms. Except for the fuel-injected 1985 Limited and 1986 GL1200 Special Edition, the GL1200 design incorporated a diaphragm onto the carburetor slide of each of the GL1200′s four carburetors. A pinch or tear of the diaphragm or atrophy of the diaphragm’s material will allow excess air into the carburetors, forcing owners to adjust their carbs for richer fuel.
The two carburetors of the GL1500 also incorporate the carburetor slide diaphragm that is still currently available at Honda as OEM , 16111-MY4-000, and sells for $120.00. Saber Cycle now offers the carburetor slide diaphragm by Barracuda Bike Parts because nobody knows when Honda will decide to obsolete this critical part.
