frankd Posted August 25, 2006 Share #2 Posted August 25, 2006 In the '83 sales literature, they said that it was supposed to increase the low speed gas mileage. Link to comment Share on other sites More sharing options...
fixit3546 Posted August 26, 2006 Share #3 Posted August 26, 2006 Dont really know, I do but i dont know how ta splainit. Took mine off and did the Jason mod, saves me 1/2 Lb. of weight overall and added about 47 Mph to my top speed...............WOW . BTW, read the disclaimer at the bottom; but I really did do the jason mod and got rid of the chamber. And I'm satisfied with the performance. I average between 38 - 43 Mpg depending on how I ride.
