Breather kit for the sidewise mounting of 2 cranecase filters at the right side of the battery. Both filters are screwed with a spacer at a precise stainless steel plate. The battery has to be demounted and 2 new holes have to be drilled. The function of the Breather Valves is also guarantied by the 2 filters and the use of as long as possible tubes. For all BUELL X1 models.
