I changed oil about 2,000 miles ago from GN4 to Delo 400, 15w-40. I know Delo has a small amount of moly, which of course may cause the clutch to slip if in large enough quantities. Many Wingers like Delo or other diesal oils such as Rotella and I am unaware of any problems they have had. I have been carefully paying attention to the clutch (friction zone) and gear shifting. I have not noticed any difference at all with the clutch (shifting gears & friction zone). Shifting with the foot shifter has been noticeably smoother since I change the oil to Delo and has been consistent.
As I was sitting on the bike allowing it to warm up today (on center stand), my daughter told me the rear tire was moving. I got off the bike, engine still running, and noticed the rear tire was moving very slowly (in the direction of forward travel). It turned about 1/2 rotation then stopped. A few seconds later, it began moving again, maybe 1/4 to 1/2 rotation then stopped again. I went ahead and took the bike out and did not notice anything strange with the clutch or shifter.
Could this be a symptom of "clutch slippage" we hear about ? Based on the rear wheel moving at idle (in neutral) is there anything to be concerned about ?
Thanks for your guidance.
