gt14rider 1,047 #1 Posted 7 hours ago Hi all, got a question about valve rotators. Doing a valve job on a k181, is it worth changing springs and adding rotators or just leave it alone. 1 Share this post Link to post Share on other sites

gt14rider 1,047 #4 Posted 6 hours ago The reason is I'm right there, had to change the cam(broke in half). Got new valves, replacing valve springs 230010. springs are shorter for the rotator 230168-s 1 Share this post Link to post Share on other sites
