Have you guys noticed that Kawasaki stopped making the FH451V engine as well as all of the single cylinder mowers? I was on their web-site earlier and noticed this. Reason I ask is because I have a 2003 Kawasaki FH451V 15HP V-Twin engine on my 2003 48" Bob-Cat mower (which I love!), and I'm wondering if I should be concerned about getting parts for it the engine for example air filters. Should I stock up on parts like air filters the next time I am at my dealer, or will they continue to make parts for it and the other engine models that are no more manufactured? Thanks in advance.
