Ha ha, I love Harleys but I have to agree with Fred, I had a 1984 Iron head sporty and it was a lovely thing, started first time every time, handled well and stopped as good as anything made in Japan at the time.
My mate Davey on the other hand had a 1979 XLH that must have been built late on a Friday, by the morning shift. He had all sorts of problems with it, but to be fair, it'd done a lot of miles.
I suppose the good thing is that there is so much in the way of after-market and genuine Harley parts available to make them much better than they were when they were new, and they are so simple to work on, even compared to an old SOHC4, and are great fun to ride.
I'd buy another one, but I want my old bike back, I sold it too early and I'm still suffering from separation anxiety..........
