| + | There was a running change to new style hydraulic lifters in 1986 for Sportsters. ((1986-1990 HD Sportster FSM pg 3-44)) \\ | ||
| + | They were the same as those used in 1340cc engines beginning in the 1986 model year. \\ | ||
| + | This change was made to allow for one component to service the entire product line. \\ | ||

| + | But if you're upgrading to bigger cams, anything more than .600 lift has too small a base circle. ((rocketmangb of the XLFORUM http://xlforum.net/forums/showthread.php?p=5613140&highlight=anti+rotation#post5613140)) \\ | ||
| + | (and they will nearly drop out of the ARDs and they can also spin away from them) \\ | ||
| + | The big issue is that they turn sideways with the roller not turning on the cam lobe. \\ | ||
