IMHO, Haynes have been living in the past for years now. Pictures are generally of poor quality, grainy black and white. Also I think that Haynes go into too much depth. The average home mechanic, whom one would expect to be the main Haynes customer, will not need info on different piston selection grades. What percentage of home mechanics will actually take on a full engine disassembly and rebuild. There are also debatable instances of mis-information such as “ handlebar switches are generally reliable “ when lots of RT owners will have experience of very un-reliable switches. There used to be manuals by Clymer but I haven’t seen them around for some time now. On the plus side, Haynes are relatively cheap. A quick ebay search has shown that a Clymer manual is available for the Hexhead RT but nothing coming up for the Twincam or later W.C model.
