TroubleShooting Bike bitsBasic problems and possible causes.
From HD manual so should be Ok!.

Tips
This section should be Dr. Smutty's Bike Surgery cos he's the only contributor. So a big Pat on the back (which I'm told is only slightly better than a hefty spanner on the nuts) to Smutty.

Motor engines gif
Will be added to currently its only got Evo Cylinder Head diagram + Head Bolt Tightening sequence. (From HD manual).

When you want to go past what's in your HD manual then you need a good spanner man OR a good book to help you on the way - this book could help and Amazon have it at a good price. Click, have a look at the reviews and you can even buy it :-).
101 Harley-Davidson Performance Projects : For Evolution Big Twins and Sportsters There's more than enough in it to occupy you over the dark winter months and YES I have bought it!!.

Click here to see Amazons list of HD Books. There's some good technical ones amongst the coffee table picture books.

HD Model Letters- aka Alphaspaghetti
HD have used lots of letters to designate the different bikes below is an overview of some, which might (probably not) help to identify more recent bikes - so I don't need any mail telling me what other letters have been used, when, and for which bikes. Remember the year of manufacture is also needed for parts e.g. '89 FXSTC.
