on my bike level while filling it up when the pump shuts off. I then pull back vapor seal to top it off to the plate and not overfill it due to heat and expansion of fuel. I would think during the break in period it gets not as good miles per gallon as the engine breaks in that increases. I don't know this to be true but seems like Mechanical things need to get moving together and broken in to get smoother. Like a good shotgun or bolt action rifle. I feel personal that at first my bike went through more gas. The engine had that new engine burning smell and sometimes it didn't start as good. I would have to hold the start button longer because I didn't start the first time. All that has gone away along with bad gas milage. And I noticed my average miles per gallon has gone up on my trips. I'm at 823 miles now and the bikes smooth as butter engine wise and gear shifter is too. Today I just passed my CA DMV circus(circles and cone test) it's down the street from my house and been going to practice cones and circles before my bike rides around town. My hands start to cramp up if I spend to much time on it like 10 min and I'm off to the hills. in case I join a circus circles are good. I think the test is weird and after driving 823 miles and pulling up to DMV and doing the cone and circles test today. it wasn't to hard and at the same time not really easy takes some skill. People who Didn't Pass complained that the test is not practical. I said you have to practice the coarse over and over. first hand full of times I couldn't do it. I kept going back and practicing. or you go to a certified Motorcycle program to learn more before getting there lic. My self would like to take the class just to learn more. You really don't learn anything about driving in the real world going around cones and circles in a parking lot. sorry got off track there but I'm so excited to have my lic now.
It's riding. Not driving. You drive a car and ride a bike lol. But yeah I agree the DMV road test is dumb. I did it even after taking the BRC. California won't recognize a BRC taken out of state and I did mine when I was still stationed overseas. I used to go to the DMV to practice and was like " this is impossible" the first few times. I passed on the actual but I sill think it's stupid. They fail you putting your foot down, make you do two circles, barely pass 25 mph and a bunch of other stuff that I don't think actually gets anyone ready for the street.
As far as break in, the motors are already ran at the factory before shipping to dealerships, so I don't really think break in period is a real thing. I think it's more for the new owner to get used to the bikes characteristics and limits the owner to certain rpms and speed over time so you aren't wfo from day one. I know I certainly did not follow the manuals recommended break in for any of my new bikes.
Back on topic, I don't think the dealership actually filled all the way to the top. At any rate, that doesn't really matter and the best thing to do is fill up, visually verify that it's full, and manually track your fuel economy.
