The paper element is about the finest screening material you can get. I bought a red, opaque, plastic filter, with a metal screen filter element a few years ago, because I could not find the paper filters in the small size I needed. I regret that. So far, no issues... (Knocks on wood!) I need to change mine out this year, before anything gets past it.
Took mine out today. Ran like a champ! Tried to fire up my Voyager, luxury touring machine: the choke cable stuck, I pushed harder, and it broke... The
1979 APJB put the 1993 uber-touring machine to shame. I love my Honda. The Kawasaki has a bullet-proof reputation, but it still comes in second place to the legendary Honda Super-Bike. Rock on, Honda!
