where can one find the FACTORY repair manual for the various ducs?st2lemans said:Yes, LTs books are good. However, they are not a replacement for a repeair manual, but rather a supplement (even LT, the author, points that out). I prefer the factory manual to the Haynes.
In particular, the valve adjustment procedure is explained very well. And he has a nice diagram showing which bolt lengths go in which hole in the alternator cover, which is great!
