On this board I've heard a few members mention timing hammer and how Edge products are set up in such a way as to cause it. What is it? Is it just an annoyance, or is it detrimental to the motor. Do all EZ's cause it or just new ones? I do notice that in trucks that are equipped w/ an EZ there is a definite sound and change in vibration that starts at about 1/2 to 3/4 throttle that sounds like the motor is just making power. Is this the hamma?
