-Below is a parts list for a remote oil filter setup although it's not a kit per say; ((HolyHandGrenade of the XLFORUM ​http://​xlforum.net/​forums/showthread.php?​t=1189337)) \\+The stock oil filter (HD 63782-80T) is the small one that is usually used on custom bikes. Chrome or black can be found. ((IronMick of the XLFORUM https://​www.xlforum.net/​forum/​sportster-motorcycle-forum/​sportster-motorcycle-era-specific-and-model-specific/​ironhead-sportster-motorcycle-talk-1957-1985/​78212-67-ironhead-oil-routing?​t=563241)) \\ 
 + 
 +However, it is also commonly known that the more oil you hold, the more motor heat can be transferred to dissipate that heat. \\ 
 +Race bikes have huge oil tanks for that reason. ((Monte03 of the XLFORUM https://​www.xlforum.net/​forum/​sportster-motorcycle-forum/​sportster-motorcycle-era-specific-and-model-specific/​ironhead-sportster-motorcycle-talk-1957-1985/​78212-67-ironhead-oil-routing?​t=563241)) \\ 
 +If you go the filter route, be sure to purge the lines by bleeding the pump front nipple first while running. \\ 
 +Then take the return line and place it into a pail before you connect to the barb tank fitting so you assure a complete circle has been made. 
 + 
 +====== Plumbing to Oil Filter ====== 
 +**Note**: On all spin on oil filters, dirty oil goes in the outside of the filter. Clean oil comes out the center. (( ryder rick of the XLFORUM https://​www.xlforum.net/​forum/​sportster-motorcycle-forum/​sportster-motorcycle-era-specific-and-model-specific/​ironhead-sportster-motorcycle-talk-1957-1985/​192457-oil-line-connecting-oil-filter-late-84/​page2?​highlight=oil+filter+bracket#​post4166360)) \\ 
 +If you are not sure, start the motor momentarily with the filter off and if oil is pumped out the center port, you have it backwards.  
 + 
 +====== In-Tank to External Spin-on Filter Conversion and Plumbing for Ironheads ====== 
 +The 1978 parts catalog lists an external oil filter kit (63795-77) for 77-78 models. Filter mounts on an (included) chrome left lower front motor mount (similar to the 82-E84 mount). \\ 
 +Also in the kit is a chrome oil filter (63796- 77A), hose fitting (63792-77), length of hose, 3 hose clamps (9946) and 3 cable straps. \\
