So the selection of pod filters for the cb500/550 is limited.
K&N makes a set, but they cost around $200

When i took a look at their specs, they were 3"O.D. with a 2" height.
Fortunate for the cb500/550 the size of the flange needed to fit the O.D. of the carbs is 39mm, which works out to be 1.53". As it turns out, a piece of flexible rubber hose with an I.D. of 1.5" fits on the carbs snugly.
With all this in mind, i figured it would be simple enough to make my own pod filters using K&N's dimensions.
First thing i had to find was a container with a 3" diameter. I had an idea to use a jar for holding bulk spices but i couldn't find anything the right size. I took a trip to a craft store and they had candles in metal tins that were exactly 3".
So i picked up 8 of these for $6. The paisley print alone must add 2hp?
Next i had to find an air filter with a total height equal to or less than 2". Spent a bit of time at the auto parts store and found this.
I picked up 2 for $10, and at the same time grabbed a pair of tin snips for $20.
With a little bit of math and a few bloody fingers, i made my self a ring of filter material.
While cutting i was sure to leave some extra filter material on the inside and some metal on the outside so the materials could overlap and make as good a seal as possible. The overall length of the filter material was 9". I cut it at 10" to leave my self some room to bevel the edge and overlap the filter and metal screen.
I marked the other part of the candle tin and trimmed it down to the same shoulder height as the lid.
And with that i've got my self a pod filter.
So with a total of $36 invested i'm well on my way to having a set of pod filters.
I've still got to make 3 more and drill my holes for the manifolds to the carbs, as well as fasten the filter material to the container. I'm not sure if i'm going to glue it in or put some kind of bolt from one of the ends to the other so i can swap out the filter material without having to make a whole new set.
