Sorry, I asked this a month ago and now the post is gone. Going to finally change out the next couple of days. I'll be riding in weather down to 10F. Can't remember if it was 14W40 or 5W50 (or maybe neither of those!). Bike is a 94 R1100RS. Also going to change tranny and rear while I'm at it. Any recommendations for that oil.
