Man I love my 2004 Big Dog Chopper with 117 S&S & not to many issues. Has wire plus harness & just got new Switch Control Module but now is cutting out badly from 3000 to 4000 RPM's i am fairly sharp but this issue is really working me over. Is it possible that it is my Thundeheart ignition or my key switch is fairly loose can it be shorting out? Please e-mail with any help! Thanks! I sure hope you get your bike fixed I understand how irritating this can be! I have an awesome mechanic he's fair & honest but some things I just wanna fix! rickvutley@ yahoo.com
