| ====== Internal Comparisons ====== |
You can interchange some covers if you are not concerned about the look of a stocker for your year bike (better resale trying to stay stock).

|
| Also be aware that some covers had the round cut out for the electric starter XLH that came out in 1967. \\ |
|
| (so the cam cover and the right case half are a match in tolerances) \\ |
|
52-78 cover had only one breather port at 6:00. ((Dr Dick of the XLFORUM httphttps://www.xlforum.net/forumsforum/showthread.phpsportster-motorcycle-forum/sportster-motorcycle-era-specific-and-model-specific/ironhead-sportster-motorcycle-talk-1957-1985/172350-77-breather-please-view-pics/page2?t=1845601&page=2)) \\ |
| 79-85 had two. One at 6:00 and one at 10:00. \\ |
| 52-76 uses .625" pinion bushing bore. \\ |
| 77-85 uses .562" pinion bushing bore. \\ |

| ====== 1957-1970 Cam Covers ====== |
1957 thru 1970 Sportsters had cams designed for an ignition to be mounted on top of the cam cover. ((Monte03 of the XLFORUM httphttps://www.xlforum.net/forumsforum/showthread.phpsportster-motorcycle-forum/sportster-motorcycle-era-specific-and-model-specific/ironhead-sportster-motorcycle-talk-1957-1985/52221-cams-cover-interchange?t=230843)) \\ |
| These cams are not interchangeable with post 1971 motors (what can be called the 'cone' cam cover). \\ |
| Early XLs had XL cams, 1966 thru the 1970s had hotter cams known as P cams. \\ |
|
| P cams are frequently seen for sale on ebay. \\ |
| When hunting for parts you want to ask, "Pre 1971 or Post 1971" for cams and covers including the sprocket cover. \\ |
