Hey guys new member here... I've got a millennium edition rx that I just burnt the rear piston on it Sunday afternoon... I know this is probably unrelated to that since that is most likely cause by a lean condition..... but I digress. I have an oil block off and premix using 93 octane fuel. I've been mixing at about 40:1.... I've been told that is to rich and to back down to 50:1... I don't know but that sound pretty lean to me. Also I'm currently using royal purple HP 2c 2cycle oil... Good or bad???? I was also told this was the worst oil I could be using... Just curious and thanks for y'all's input!!
