    Unauthorised Guide To Harley Davidson
  

*by D***S on Reviewed in the United Kingdom on 24 August 2011*

I found the book very interesting but it is quite hard going at times. Then again, it's not a novel, it is a technical manual. It did give me a lot of information on HD engines and the problems that beset them in the past, and how they were overcome. The book is all that I thought it would be but it is not light reading - I go back frequently to look up particular sections although that is generally to the actual paperback - I have the kindle edition also but oily hands on my stepdaughters kindle would not be appreciated. The book is not really a "how to" manual as the Clymer or Haynes would be more an in depth study of that particular developement of the HD engine.I really like the book, I've read reviews that it is not an easy read, being a bit hard going at times - I felt it was also a bit lacking in character development as well, but then it is a technical manual so what would you expect - some of what it deals with is quite complex.If you are a Harley fan and interested in the evolution of motorcycle engines this is the book for you - the Kindle edition is cheaper than the paperback

    Like all the Donny Petersen stuff it's excellent
  

*by S***Y on Reviewed in the United Kingdom on 12 April 2015*

Like all the Donny Petersen stuff it's excellent. Not a workshop manual in any way. It is full of very deep discussion & description of the workings (and breakings) of the Twincam. If you are interested & understand in the insides of the Twincam  & the ways of Harley motors this is for you. Lots of stuff about running your bike, oils in particular. I bought it (& the other Petersen Tech Guides) after reading various extracts that were reproduced in AIM to me they are all well written and detailed. Recommended

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Amazing detail
  

*by E***E on Reviewed in the United Kingdom on 17 January 2017*

Amazingly detailed but not completely free from errors and weird typeface changes. Recommended overall though.
