Easy rider, I love the reed box, how did it perform? Did you slot the piston? And you can add a port over the top of the piston in the intake port that you can't do with the stock intake! Wow I was wondering when this was going to be done. I was going to make one but the hardest part was the reed cage. I love the pipe, but I think you are giving away a lot of the performance with the stock muffler on the rear, it needs a stinger that is tuned. When you get the length you then put a glass muffler the same length. Have fun, Dave
PS: You can put a boost bottle on the piston side of the reeds, When the reeds slam closed that is the pulse the bottle uses. That is the combo that is supposed to work! Is there a link to the manufacture?
