After the carburetors are installed on the bike and connected to a fuel source, use the wet adjustment procedure to finalize the float levels.įor European/Canadian XJ600/Diversion Carbs (Mikuni BDS28): Continue to remove and adjust the tang until the float level is within spec:
Refit the float and remeasure the height. Bend it in small increments a little bit goes a long way: Grasp the tab with a pair of pliars and very carefully bend it. The location of this tab sets the height of the float: To adjust the float height, remove the float pin and remove the float: In the following photo, the float heights are too high and need to be adjusted. The float needle should not be compressed. Mikuni carburetors, commonly installed on motorcycles ranging from small single cylinder dirt bikes to V-Twin motorcycles, have a plastic float to regulate fuel consumption. This measurement should be taken when the float just contacts the float-needle. The float height should be beneath the edge of the caliper. Measure from the gasket surface to the top of the float. I set the caliper to 7.2mm and locked it. I used a dial caliper with a depth gauge to verify this setting. I chose to average these two and set them for 7.2mm: The specified range for float heights is 6.2 to 8.2mm. Here's the procedure as laid out in the FSM: The factory specification for dry float heights is 6.2 to 8.2 mm or 0.24" to 0.32". This is used to get them in the ballpark before setting them using the more-accurate wet method.įor US/Australia Seca II Carbs (Mikuni BDS26): Preliminary Float Height Setting (Benchtop or dry Method):Īfter a thorough disassembly and cleaning of the carburetors, you should set the float height on the bench.
