As the old saying goes, "The road to hell is paved with good intentions." So ask yourself: What is the first thing to get changed on a flathead? Usually it's bolting on a dual or triple manifold. Then you toss the stocker and with it the oil bath filter any hope of ever really cleaning the air your engine uses. Maybe you'll just use screens to keep the bugs out? Or maybe those screen+foam things to fool yourself into thinking the air will actually be a little cleaner? The one thing you're DEFINITELY going to do is change the oil religiously because well... you just will. Well... I don't. So I'm trying to find ways to make my oil last longer. I want filter(s) that work and don't look stupid. Ideas?
