+====== Related Manuals and Documentation ======
+Below are some suggestions for manuals for your ride. \\
+__You should have, at minimum, a Factory Service Manual (FSM) and a Factory Parts Catalog for your year model__. \\
+**Factory Service Manuals (FSM)**; \\
+The FSM will have the most accurate information, procedures and specs. \\
+Clymer and Haynes make service manuals also for Sportsters but some of the information is in error to the factory FSMs. \\
+And some of the information in the aftermarket manuals is vague in information or procedures but they may have more pictures. \\
+So it is generally said you can get use from both an aftermarket manual and the factory service manuals but get the factory manual first. \\
+[[techtalk:miscres:miscres10|Click Here]] to view the Factory Service Manual page in the Sportsterpedia. \\
+**Parts Catalogs**; \\
+The Parts Catalog has part numbers of course but it also has exploded parts views. \\
+However, IT IS NOT INTENDED TO BE AN ASSEMBLY MANUAL. \\
+And some of the exploded views are confusing or not related to each other on the same pages. \\
+But, all in all, the exploded views do help finding what goes where. \\
+Most of the fasteners listed in the relevant parts catalog individual pages have thread sizes and lengths also in case you need those. \\
+**Note: ALL 1957-1978 PARTS CATALOGS LIST PARTS FOR PREVIOUS YEARS**. \\ Below is a simple list of original and "latest edition parts catalogs.
+The in-between year books may show different part numbers for the same year model bike. \\
+[[techtalk:miscres:miscres12|Click Here]] to see the Factory Parts Catalog page in the Sportsterpedia for parts catalog uses and a full list of parts catalog numbers from 1957 to present. \\
+(complete list of other parts catalogs and supplement catalogs that pertain to each year model on the bottom of that page) \\
+Some often acquire several year model parts catalogs and that page will help you decide which ones are right for you. \\

+===== The Ironhead Multi-Year Parts Catalog Curse =====
+Below is a summary of an article on the Sportsterpedia Parts Catalogs page regarding parts book errors. \\
+You can also read the full article from this link: [[techtalk:miscres:miscres12#the_ironhead_multi-year_parts_catalog_curse|The Ironhead Multi-Year Parts Catalog Curse]]. \\
+Due to all of the errors and non corrected editions, it's always a good idea to acquire several year parts catalogs surrounding your year model. \\
+Which year catalogs you'll need will depend on many factors but the main Parts Catalog page in the Sportsterpedia will help you decide which ones you need. \\
+[[techtalk:miscres:miscres12|Click Here]] to see the Parts Catalog page. A full chart of all the parts catalogs made for Ironheads is at the bottom of the page. \\
+  * Not all multi-year catalogs will list factory installed parts on your bike.
+  * You may need several year catalogs to determine factory installed parts for your year model.
+  * Some parts first appeared or only appeared in Parts Supplements, Service Bulletins or other literature
+  * Later catalogs may show parts for older models that were never factory installed on them.
+  * Some catalogs have missing parts and/or missing models in some parts listings.
+  * Some illustrations do not have a part number listed.
+  * Drawings may or may not look like your part number.
+  * Some exploded parts diagrams show the assembly in the wrong order or missing pieces.
+  * There may be misleading information about parts that fit your year model.
+  * Fastener lengths and thread pitch may change depending on catalog used.
+  * The MoCo knew about and tried to correct at least some of the parts catalog mistakes.
+===== Search the Sportsterpedia =====
+See the Navigation menu on the upper left of this page. \\
