| ====== Installing a 1986 Primary Cover on a L1984-1985 Sportster ====== |
This primary cover swap was done by XLForum member, 85IRONDIRT, on a 1985 XLH 1000. ((Link to thread from the XLF httphttps://www.xlforum.net/forumsforum/showthread.phpsportster-motorcycle-forum/sportster-motorcycle-era-specific-and-model-specific/ironhead-sportster-motorcycle-talk-1957-1985/201772-late-84-85-primary-cover-to-86-90-cover?t=2078880)) \\ |
