2 things you can do without altering the tank.
1) switch to Higher octane fuel (I find I get better milage, if not any more speed)
2) Modify the fuel cap tunnel so you can fill the tank fully. (I get around 10-15 miles more to reserve this way).
If you don't have ABS you can also have the tank modified so that it dips into the hole where the ABS would sit - that will give you (at a guess) 3 more litres capacity. (I'm tempted...)
Of course you can also ride in a smoother/more gentle manner - with the first two mods above, and gentle riding (it's winter and it's COLD!) I'm getting around 160+ miles to reserve, which will probably give me about 55 extra miles of reserve if I chose to use it.

I did the search, but can not find the instructions how to modify the fuel cap tunnel. Remember something about drilling the hole, but where???riceburner wrote:2 things you can do without altering the tank.

If anybody got a pic or instructions, I would appreciate the help.
Thanks.

To those with early yellow lights - Your light adjustment is bad or your bike needs tuning ....really.
Any oilhead with a reasonable state of tune and ridden in any fashion other than WOT will go 160 to 180 miles before the yellow light comes on.
I checked many times over with any type of gas and in various parts of the US and could set my watch on the yellow light coming on between 172 to 176 miles. The fill was always 4.1 to 4.2 gallons, meaning you had one gallon left. Taking inventory and accountng for the split in the tank that leaves a long 20 miles to look for gas before you start to worry.
I'm against adding external fuel tanks, they are dangerous, even if it is a fuel cell, because at ~8 lbs/gallon it will affect significantly the balance of the bike.....obviously much more so if you carry luggage. In addition, anyone that rides needs to strech every couple of hours, if you want to enjoy good circulation in your old age.
So if you ride at 80 - 90 mph, you need to stop about every two hours.....you see everything works....and the number one too.....just my 2 cents.

what kind of revs were you riding at? I regularly (as in daily) am going over 80 in winter, and over 100mph in summer, just on my commute. I also tend to ride reasonably rapidly (not flat out, but rapidly) on weekends and touring. Fuel usage is going to depend a LOT on how the bike is used.boxermania wrote:To those with early yellow lights - Your light adjustment is bad or your bike needs tuning ....really.

Although I agree that 100 miles to reserve is scary!
(and my light is deffo green.

Most of my driving was done at 3500 rpm to 4500 rpm, which in my old bike equated to an indicated 70 mph to 90 mph.....ocassionally over that when passing on the slab.
When my buddy (R1200C) and I traveled from Baton Rouge to New Orleans, 63 miles away to catch some Thai food, we used to do it around 42 minutes for an average of 90 mph.
No, I'm not proud of our accomplishments, we made up for it on the way back, with a full tummy, at a law abiding 70 mph.....

Before I bought my RR, I tried out a GS-ADV and, while thinking the extra range was nice, didn't like the top-heaviness the tank imparted to the bike, which was little taller than my RR too, so that would also affect the handling. All in all, I wouldn't want that thing on my bike, I like the nimbleness of a low CG!

hmm - I'm now thinking that the top gear on my bike must be shorter than I thought - I know I'm revving higher than that at 80-90.boxermania wrote:riceburner
