Oil Check on 2020 R3R

They don't usually come loose if properly installed. "Hand tight is good. If it leaks that's just more service." Yes they will loosen and leak.

If you do "allow" a dealer to change your oil, please, do the cold oil check before leaving the place. You might be very surprised. They have short changed many a bike by improper procedure. And check filter tightness when you have a chance.
 
Yep, I just had the 20k service done, checked it cold the next morning and it almost took a whole qt to get to halfway on the dipstick.
 
I agree about checking the oil using the procedure in the book and following it to the letter. Even tweaking the throttle during the 90 second warmup will screw it up. Any deviation will show a high level. When I finally followed the book to the letter I got a correct reading. I was about a 1/2 quart down. All subsequent readings have been consistant and spot on. Crazy stuff, but it is what it is...
