I'm looking at a 2003 Road Star 1600 a friend has for sale. The bike has about 25000 miles on it and its in show room condition. The owner looked after that bike like no other I'm sure, in fact it's cleaner than most new ones. The question I have Is I drove it last night and I noticed the motor seamed a little louder than my 800 Vulcan I own. I found it ticky and vibrated more than I'm used to. He would not been hard on it at all and is this normal for these motors? I read that they are louder than the water cooled motors but before I buy just wondering if this is normal? Hope to hear from some owners out there. Thanks.
