I recently bought a 2002 Sportster 1200. It`s had only 7,000 miles on it. I brought it to the local HD dealer and had it´s 10.000 scheduled service done on it. And I was going to use Synthetic oil but the service manager he he would,nt in a Sportster because they are ready a typicaly noisy motor! Does anyone else find that to be the case?
