09 Ultra- engine light came on on me the other day and didn't seem to be any running probs. I got home,pulled up PO577 cruise input high code,so I took bike back out and tried cruise and sure enough it wouldn't set. After trying several times it set,eng. lt. went out, then approx. 5 seconds later cruise let go and eng. lt. back on. Any thoughts? BTW,First timer here,been taking all the great suggestions -(Oils,tfi,etc.) and using them. Great site.
