Got a local master machanic that has owned about 10-12 HD's and now has a auto repair place, real sharp guy. I was going to ask him if he would maintain my 2006 HD Dyna Lowrider if I bought the service manual. If he says he will do it I will save $$$ and feel like the work was done right. I would this effect my warranty? Does he need any special tools to do the 1K and 5K maintance?
