Ok so the scout I have never had a problem with the S&S engine. The top motor mount did have to be replaced, this is a known issue with the S&S bikes.
The 03 Chief I bought off ebay from a HD dealer in Minnesota for about $10600 and 6k miles on it knowing full well I would have to have the engine rebuilt more than likely at some time. Rode it for a year and had no problems whatsoever but knowing the problems there were with them, every time a rock hit the fender or a noise was there it was OMG are the bearings trashing out? Talk about making for unpleasant riding at times!
I opted to send mine to Joe Malfa at
http://jamltd.com/ and have him do his performance build on it which takes care of the problem with the crank bearings due to bad castings. She runs like a top and will eat a screamin eagle up very quickly:D There are also 3 other places that rebuild the engines
