OK, Helix owners.... WHERE do I get Helix parts?? Shall I go to the local Honda dealer? Or online? All I need is that stupid gasket on the muffler. My Helix is back-firing on compression and getting louder every day !!
One part is the larger gasket and one is the small. One should never have to be change and the other can be.... One is: 18391-MB0-891 and the other is 18291-KS4-690. WHICH IS IT??
