I ordered a copperhead module for my 03 650 and after talking with them they claim I cannot run that one on my brute 750??? Is this true they claim the spark firing is different. The Dyna I had ran fine in either? Are they just wanting another sale or is there truth to there claims? Thanks

 

I have heard the same story. I do not know for fact that it is true, but I have heard that a number of different times.
