I have been tossing around the idea of purchasing an old H-D shovelhead. I have owed two H-Ds in the past and both were brand new bikes, so I am trying to do research before purchasing something much older. Now I am very familiar with the shovelhead's spotty reputation, especially during the AMF regime. Did the shovelhead bikes magically improve after the buy back from AMF? I would like some practical information from anyone who has experience with these bikes. This bike would be used primarily for commuting to work everyday (100 miles round trip), and of course the occasional pleasure ride. So advice in areas like vibration, chain adjustments, how often things have to be tightened, general reliability/practicality as a commuter, etc. would be appreciated. I have been looking at bikes from the mid 1970s to the early 1980s. I prefer a bike with disc brakes versus drum and shoe. Does having a belt drive make any difference with a shovelhead? Thanks.
