 There was a running change to new style hydraulic lifters in 1986 for Sportsters. ((1986-1990 HD Sportster FSM pg 3-44)) \\

+These work OK for stock cams. \\
+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. \\
+(which can heat up and destroy the roller and the cam lobe) \\
