I was also surprised to find for the 600 mile service they sold me 4 quarts of GN4 10-40, figured it came shipped with HP-4 but the manual recommends GN-4. What's also interesting is they make a big point this model must use JASO MA compliant engine oil but it is my understanding GN-4 isn't certified to this standard?

Break in oil sample is at the lab for analysis so we'll see in about 3 weeks what comes out.

 

Synthetic oil labeled "energy conserving" for car has friction modifier in it, which makes clutch slip. As long as it's MA complient, it's fine to use in our motorcycles.
