First ride last night since changing to full synthetic oil. I went with Castrol 10w50. It was only a dollar more than the regular stuff I get and on sale. I figured since my bike has been so good to me I'd return the favor. Was about 75 or so and at night so it wasn't even that hot but I noticed at a red light temp needle was right on the line. It's usually about a toothpicks width below it. The fans also kicked on which never happens? Just curious if anybody's bike ran a lil hotter when they changed over to full synthetic? I was using Castrol 20w50 semi synthetic.
This is what I used
