Looks like you and your dealer are using car oil.
I can't find that viscosity in MC specific Mobil 1.

Mobil-1 MC Oil



My dealer doesn't use any Mobil 1 oil. They do use 15W/50 - not sure which brand, but you can bet it's the correct oil. When I asked what I could buy to top it off (I'm 40 miles away), he said I needed to add 15W-50 and Mobil 1 fully synthetic would be ok. The only 15W-50 I could find in a hurry was Mobil 1 Extended Performance. I noticed the 15W/50 wasn't listed in the above link under the Extended Performance but they definitely make it and O'Rielly stores sell it. Maybe they also make a MC oil 15W-50.

I'm leaving my bike for 4 year service this week and do plan to get a quart from them (what they use) to top it off. Hopefully, once the breather is fixed, I won't have to add any.
