 +  * **Accelerator pump rod length**: A number of Screaming Eagle carb kits (91731-85A),​ packaged during March of 1988 (3/88 date code), contained carburetors with accelerator pump rods that were too short. The incorrect pump rods were only 2.35" long, end to end, and completely disabled the accelerator pump and caused the engine to stumble upon fast acceleration. The correct length pump rod (27374-88) is 2.55". ((HD Service Bulletin #M-961 dated April 8, 1988)) 
 +  * Dealers were to check their parts stock and replace any pump rods that measured short and also check the pump rod length on any motorcycles that exhibited a stumble upon acceleration.
