Any body know where I can download a free repair manual for Harley Davidson Sportster 1979 XLCH and 1972?

i don’t know of a free website for this, but for a
price go to http://www.jpcycles.com
enter harley service manual in the search box. they have the genuine harley manuals as well as many parts for your old sporty. good luck.
