First just wanted all you to know your input is much appreciated and there is tons of knowledge here. My question and concern is this. I have an 09 hertiage with about 3000 miles on it and have done most of the readusting and change of oils you recommend. It is still stock which does not bother me all all. But I keep hearing if I don't add a fuel pack to improve the mixture that I will eventually burn up my motor. Is this true or just a miff? This is my first and will not be my last harley. I am an old vet and believe in american made.
