Obviously, city vs highway speeds and stop and go traffic would greatly impact the range you can go once the "Low Fuel" light comes on... but on average, how long do you guys go before filling up once the light comes on?

I've only had the bike 2 days, so I haven't had much time to really get to know/familiar with it... but I was just wondering when the light came on this morning on my way to work.

 

Ignore the gas light, it's a piece of junk. Mine comes on all the time with no real consistency.

I suggest you get a small container of fuel, fill the tank, reset the odometer, and see how many miles you get before it runs dry.

With my 3.3gal tank, I think I can get about 100'ish miles before I reach the danger zone.

 

Also... I don't have a manual yet (I'm picking it up from the previous owner today) but what type of fuel is recommended for my 2010 Iron?

 

I've always used 91 in my bikes...be it a sports bike or my Harley.

As for the low fuel light I wouldn't trust it. Use your odometer as your fuel gauge.

I personally fill er' up all the time. Even if it is only a gallon I top off. Better to have it and not need it than need it and not have it.

 

When my low fuel light comes on it holds 2.3 gallons so I figure it comes on when I'm down to 1 gal, took a chance and went 25 miles with the light on and filled up, took 2.8....as far as fuel goes I think 91octane or greater

 

91 premium is probably your best bet.

 

Here in VA,93 is offered,so that's what I put in. Non ethanol when available.

 

No fuel light on an '00 XL1200C... the trip odometer usually reads around 135 when I have to switch to reserve. Ran her completely dry at 180 miles on a road trip once - underestimated distance to next fuel stop/overestimated amount of reserve.

Fortunately we were within two miles of a station.

And, yes, that peanut tank holds 3.3 US gallons. Not a drop more.

 

If you have the 3.3gal tank, the light should come on when you have about .8-1 gallon left.

Mine comes on very consistently when I've used 2.1 gallons of fuel, usually at about the 100-110 mile mark.

What I recommend:

Use your trip A meter for each tank. Use trip B for whatever else you want.

Watch Trip A as if its a fuel gauge, when it hits 100, go straight to the gas station.

 

I fill up with 91 octane when I reach 135 to 150 miles on the odometer! Never gone past that with the 4.5 gal tank on the custom!
