RE: Magnum .61 RFS bottom end running temperature?
The backplate only shows slight rubbing from the conrod, but barely enough to polish the aluminium, and about the same as i have seen on other engines. Except for rubbing, what could be the cause? I was thinking maybe I'm used to 2 strokes and this is a 4 stroke quirk? what should the temp be on a properly running and setup 4 stroke?
