Whenever I fill up, I usually put in gas until it reaches the very top of the compartment, but I noticed that some of you may only fill up to the little bar in the gas tank or whatever. Is there a certain reason for that? I'm not sure if the owner's manual actually states where to fill your gas tank to.

I know that in cars, I never "top off" because gas expands in heat, so I always fill up till the nozzle clicks.

What about you guys? Anyone else fill up all the way to the top like I do and has had any problems?

 

That bar is the fill line and marks where you are supposed to fill up to.

Not sure what the ramifications of topping off are.

 

I top it off too.

Nothing's acted strangely since I've done it...?

 

i fill up till its barely covering the bar. no specific reason except it is easier to not splash gas on the bike imo.. but i have wondered what it mattered

 

Same. When it hits the bar, I'm satisfied.

Edit - from the owner's manual: "Add fuel until the level reaches the bottom of the filler neck. Avoid overfilling the tank. There should be no fuel in the filler neck."

 

Sweet. Thanks guys

 

I always top off and never have an issues. If it gets too hot it will vent itself anyway.

 

Btw, once I was trying to slowly squeeze the trigger on the nozzle to top of my gas tank when I accidents squeezed too hard and gas got into the filler neck. I saw it funnel out through that little drain hole though. I'm assume there is a tube that leads the excess gas down to the bottom of the bike, right?

 

I get another 30miles plus topping off. No problems that Im aware of.

 

Street bike tanks aren't vented like motocross tanks, are they?
