-----+====== 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 1980-1985 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. \\ 
 + 
 +**Suggested Manuals**: \\ 
 + 
 +  * **Factory Service Manual (FSM)**: 
 +    * **Original**:​ 1979 XLH/XLCH-1000 Service Manual (99484-79) 
 +    * **Latest Edition**: 1979-1985 XL/XR Models 1000cc 4-Speed Service Manual (99484-85) 
 +  * **Factory Parts Catalogs**:​ 
 +    * **Original**:​ 1979 Sportster XLH/​XLCH-1000 Parts Catalog (99451-79) 
 +      * Written in April, 1978 and should have the closest list of original parts for 1979 XLH and XLCH models. 
 +    * **Updated Edition**: 1979 Sportster XLH/​XLCH/​XLS-1000 Parts Catalog (99451-79A) 
 +      * Written in November, 1978 to include the XLS model. 
 +    * **Latest Edition**: 1979-1985 XL Models Parts Catalog (99451-85A) 
 +      * Written in 1990 and lists parts available in 1990 for 1979-1985 models. 
 +  * **Factory Owners Manual**: \\ Note: The oil tank capacity is wrong in both these manuals. Neither has been full vetted. 
 +    * **Original** (January, 1978): 1979 XL-1000/​XLCH-1000 Owners Manual (99466-79) \\ Does not include XLS models. Bike pics not correct. They are of the XLCR instead.  
 +    * **Updated Edition** (December, 1978): 1979 XL-1000/​XLCH/​XLS-1000 Owners Manual (99466-79A) \\ Revised to include XLS models.

 +===== 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. \\ 
 +From there you can go to the main Ironhead section menu, the Reference section for general and in-depth procedures, and the Misc Resources for documentation. \\

 +=== Early 1979 === 
 +Starting in 1970 thru E1979, Harley Davidson partnered with Goodyear for a new "​special"​ tires and rims for standard "high ground clearance"​ Sportster models. \\ 
 +Standard or Low Clearance models did not have the "​special"​ rims and use standard tires. \\ 
 +[[http://​www.sportsterpedia.com/​doku.php/​techtalk:​ih:​wheels01|Click Here]] for the Ironhead tires and wheels page in the Sportsterpedia for more information. \\

 +Tire pressure based on 150 lb rider. When weight is exceeded by 50 lbs or more, increase the rear by 2 lbs and front by 1 lb. \\ 
 +Repeat for each additional 50 lbs of weight. ((Harley-Davidson 1970 - 1977 Service Manual)) \\ 
 +Tires: (both the Special Goodyear and the Yokohama tire brands are all obsolete now) \\
