      Breather Bolts purchase

      I purchased the breather bolts along with the louvered air cleaner. The bolts were easy to install, just a twist of the Allen wrench. My mistake not making sure the snap ring was completely in place, and sure enough, I lost the screen that very same day when I went out for a ride. Lowbrow doesn’t sell the screen separately, so I replaced it with a couple cut down faucet aerator screens. The whole air cleaner install is quite easy and takes just a few minutes, just make sure the snap washer is seated, they actually tell you this in the video. Anyway, the air cleaner looks cool.
