| As we already mentioned, At/Ct1's only have around 3 inches to work with for an air filter set up. Here is what I came up with. I used stuff I had laying around my garage and kitchen. |
| I personally like a foam filter on a race bike. I wanted to address the long tube for the intake tract, normally used on AT1 racers,plus I was starting from sratch, so a clean slate to start. The large red filter and the cage next to it are for a CZ. Here goes, ingredeints Honda sl 125 filter element, stock, part #17211-107-020 $8 and the connecting tube #17253-107-782 $18. CZ air filter cage cut down , Dole pineapple can. 6- 3/16 short rivetts and washers. To start with. |

| I found a big aluminum washer. Actually a remnant from a hole cutout of 3/16 thickness, it fit perfect and gave the filter element cage a good mount. Next I cut some sheet metal I had laying around, formed it to the frame put a 90 degree bend in it, cut and bent the corners in on themselves, then pop rivited the folds together to keep the twisting to a minimum. |



| The Honda 125 SL connector tube was cut down about an inch. When finished it's a little like a miniature Husky filter and flows really well For a cover all I could find was an Ice cream container, so cut it to fit. Here is the finished product. |
