i have a 99 classic with a 600 isx. Lately the jakes have been hit or miss. I think the problem is with the fuel pedal. Sometimes if I put my foot on the pedal and let off fast the jakes will kick on sometimes they won’t. Sometimes just normal driving they will come on. Playing with the fuel pedal works sometimes sometimes it don’t. Anyone have a similar problem? What was the fix?
Isx jake works when it feels like it.
