Would an 04 speedy igniter work on my 03 America?




Shouldn't be a problem at all. The Speedmaster didn't go to 865cc until 2005. When my igniter box went Tango Uniform, I put Dwight's 2002 Bonneville America box in my 03 Speedmaster and it worked. An added benefit of the Speedmaster box is that the rev limit is 7,900 rpm compared to the America's 7,400.
