Anyone ever heard an 07 heritage bang when its starts up sounds like a slight back fire or maybe starter ingauging anyone else have this problem

 

Funny you should ask that I had a 07 deuce and my pops had a 07 heritage, and yes they did make a loud "bang" when you started it , Kokomo Harley just informed us there is a download that is free of charge to every one who has a 07 or 08 big twin if they request it, it has something to do with the compensator, and the stator,..call you dealer they should know what your talking about by the way my 09 train does not make that loud noise when you start it

 

where do i get the free download

 

your dealer

 

I have a loud clunk when starting and have had backfire several times since new. the down load I believe changes the timing at startup and is supposed to stop the clunking. I'll know after asking for it.
some of the 07-08 's are having compensator issues and that should also be taken up with dealer.
Both of these need to fixed before warranty it up or its on you.
