I'd use a foam type stock filter.
It won't hurt a yammie enduro to run without the battery. The battery basically supplements the lighting, i.e. blinkers are better, tail light lights without the engine, stuff like that.
Better batteries are the sealed agm ones that are used for back-up power for home alarm systems. Just take the battery to your local Batteries Plus store or the like and get one. No worrying about acid eating up the seat and battery box and the damn drains that never seem to get routed correctly.
I use a UNI filter on my yamaha's they come with the cage and sleeve that are just like stock except better.
