  1.  @TRX450RVlogger  Yamaha used them on RD250 and 400. aircooled models and the wate-rcooled RD350 (plus some models of 'Banshee) I can't remember if the YPVS used them, don't think the Brazilian made ones had them but they were dog slow restricted anyway They are basically Helmholtz resonators on the Yamaha. Those dinky little bottles are probably an attempt to modify the crankcase pressure, either increase vacuum or buffer something?
