I was disappointed when I got this book. I was surprised how small and thin it is. The information is mostly what could be siad about buying any bike, and it states some very obvious things to look for when buying a Harley big twin.I don't consider being warned about the amount of chrome and how to check it is ok to be an ESSENTIAL guide on the marque. I wanted in-depth engine and transmission faults,any problems to look for specifically,etc. I did not expect to pay money to be told that,yes,they used to leak,and they used to not stop,but things are better now. Do you remember the old bike mags where the write-ups seemed to have been done in a pub,by scribes who never got to the bit that you wanted to read?.... "Deja-vu".
