Motorcycle Repair: Air Filter, honda 305 scrambler, davidsilverspares

Question
I have a 1967 Honda 305 Scrambler motorcycle that a friend gave to me and am close to getting it on the road but I need to find a air filter.  Have been surfing the web and see that there are over 900,000 sites to go through but I don't have that kind of time.  What would be the best way to find one and is it possible to make a filter?

Answer
Well searching the web doesn't have to take that long, just narrow your search term.  Join the 305 scrambler club, and they will know where to find parts.  Or try somewhere like: http://www.classichondarestoration.com/Vintage_Honda_305_Parts.php

These guys specialize in old honda parts, or you can even make the filters yourself as described here:
