Robenstein, your exactly right - with true summer heat on us in Socal Ill be in 95+ temps all day long, I ride daily, in traffic, and hard so.........
Ive seen a few people suggest VR-1 in a 60wt - thoughts?
It only comes in a straight 60 weight, which is too thick on startup. Plus its hard to find much else beside the 10w30, 20w50, and straight 30 and 50 grades in most stores. Just run the 20w50. Harley motors unlike shared sump designs is a lot easier on the oil. Sure they get hot, but my shared sump air cooled Triumph is a lot harder on oil and it will shear it down more than your HD Twin Cam.
