A note about Orange and Tracks. Please read input from Gregg Childs below..

I am offering a hood exchange. All owners of Orange Arctic Cat 120 hoods can exchange their old (in good condition) orange hoods for a new green 120 Arctic Cat hood at zero cost! All you would pay is shipping of your old hood to me and the shipping cost of getting the new hood back to your door.(or you can certainly pick it up at my shop in Rochester, Minnesota) I am offering this package to help out the owners of these orange sleds and because of the fact that 95% of the hoods I use are for Champ sled builds and end up getting painted anyhow. So as long as the hoods are in good shape, I can use any color out there.

Also: Please inquire if interested in just purchasing a new green hood. I have plenty in stock and are offering them to all Arctic Cat racers for only $150.00 ea. Hopefully, this will help the cost issues involved with changing sled colors. I can be reached by e mail at the address below. Thank you.

P.S. I am also working daily on a new, light weight F-1 rubber track that will replace the old cleated versions. Details are in the works and more info should be available by Haydays. Interested parties stay in touch.
