Hi, just looking for little advice on 2006 GS1200 expected tank range. Had it about 8 months and love it but only manages around 120 on full tank. This seems quite low, would remapping assist in obtaining greater range? Many thanks in advance.
 
120 miles on a tank does seem quite low. I had a 2007 GS, which I think is the same as your 2006 bike. If I remember correctly I used to get around 200 miles on a tank and still had some range left to look for a gas station. The only exception to that was when I was heading into strong headwinds while traveling at 85 mph on a ride across South Dakota one year, but I think that only brought my range down to maybe 140 miles or so (it was several years ago so I'm not sure I remember accurately).

May I ask how much gas fits in your tank when you fill it after riding for 120 miles? I'm wondering if your fuel gauge is inaccurate and telling you to fill up before you really need to do so.

Many thanks for your reply Avocet. Idid wonder about the fuel gauge as sometime it does read inaccurate and catches up as I ride. Will have a look. I think I usually pit around 18 litres in.
 
Very low

The fuel tank has a capacity of 20 titres.

I have had 4 GS bikes and get roughly the same consumption.

On a run i would easily get 400 km or 250 miles.

My distance to empty light usually gave me 70 km, or about 43 miles warning when running low.

I have never run out of fuel using the distance to empty as a gauge, and usually only put around 17 liters in the bike to fill it up.

You fuel consumption does seem quiet high, but it will depend on lots of factors.

If i give mine the hurry up it will drop a fair bit, so every trip is different, and every rider is different
 
My 2010 TC does around the 190-200 mark as well.
I wouldn't consider a remap or anything like it until you find what's wrong.
What's the air filter like? Is it dirty or damp? Is it the original one!
Is the exhaust exit sooty because it's running too rich?
If it's nothing obvious, then the problem might lie elsewhere.
One of the guys on the UK GS forum has had his remapped and while he says it's very quick, it drinks fuel. Similar consumption to yours.
Maybe some chimp has already remapped it for you?
I use a Power Commander on mine and it has made it smoother and it has more torque than standard. With the de cat headers, it's now quite nippy.
Fuel consumption is slightly better than before, so improved performance does not necessarily increase fuel consumption.
Check for the obvious(cheap) first.
You know it has six gears? :wink2:
 
Hi did you ever find the solution/problem? I have the same issue.
Thanks, Mick
When did your problem start? Was it after a change to the bike was made? Did fuel economy slowly degrade or was it all of a sudden?

  • Check the caps on the vacuum ports on the throttle bodies are intact.
  • If the evap. canister is still in place make sure the hoses to and from it are in good condition.
  • Check the coil sticks for proper operation
  • Do a fuel pump pressure test
  • Check/test the O2 sensors
  • Remove any aftermarket fuel devises and/or O2 manipulators and see if fuel economy increases.
My Hexheads average for 40 to 44 MPG (US Gallon) depending on how I'm riding.

@Mixter888 providing mpg fuel economy will help, as we all fill up at different times and the old BMW fuel strips/gauges are a known issue.

I normally range from 36 mpg on 4-lane interstate to 40 mpg on 2-lane backroads.
 
For my daily PSA I'll remind our campers here that the Imperial gallon used in the UK is 25% more fuel than the gallon used here in the USA. I average about 39 mpg (US) with the best I've ever seen being about 42 mpg. Might have something to do with how I ride but regardless, I rarely push to 200 miles between fuel stops. I'm ready to get off the bike for a leg stretch and water break anyway.
 
Thanks all, sorry, got locked out of my account for ages there! Going through the steps now to check all.
