I have 'em, and I love 'em. My oil temp is usually under 200º but sometimes gets up to 230-240º in the middle of the summer when I'm really pounding it. I must have my jetting pretty good right now because it hasn't gotten over 200º in a long time. Some guys said they can't get them to stop leaking oil, mine have been on the bike for over 20K miles problem free.
