One of the things that my 2004 R1150Rt, Maria, does well is eat up miles and miles with apparently little effort and at the same time providing me with a comfortable ride.
There's been times though when the gas station I expected to be there was closed, or out of business and then it was some nervous riding on my part till I got to the next gas station. I've only run out of gas one time, and that was on Brigitta, my 1987 R80 Beemer. She was quite the pain to push the last 200 feet or so to the gas station. I can't imagine what fun it'd be to push Maria, who weighs at least 200 lbs more!
I know what you're thinking, why doesn't he just stop each time the odometer or fuel gauge indicates you're at half tank? Yeah, I could do that, but then you lose valuable riding time! That, or there's no gas station at this magical half tank mark or you just don't want to stop since the highway sign says the next one is just x number of miles away and you know you can make it!
Whatever the reason, I tend to tank up closer to the 170-180 mile mark. I know that Maria will go 200 miles no sweat without the "low fuel" warning light coming on. I also know that when the "low fuel" light comes on, I've less than a 1/2 gallon (if that) of gas left.
Yesterday, the final pieces from Kolpin came for the external plastic gas can mounting bracket that I'd bought via Ebay. The kit I bought was the wrong one for the can I already had you see, but the good folks at Kolpin comp'ed me the required pieces. Great service on their part!
A little drilling, the use of a tire iron as a support bar for now until I figure out something else and voila the gas can and bracket were mounted.
I took Maria out for a test ride of about 12 miles and everything stayed in place just fine. I carried water instead of gas for this trial run and there was evidence of a few drops of water on the side of the can and on the pillion seat when I got home.
I think getting a suitable sized O-ring and really tightening the cap should do the trick in terms of keeping stuff inside. I plan to, when carrying gasoline to only carry a bit over 1 gallon even though the capacity is 1.5 gallons. This to allow for expansion and avoid spillage.
I plan to ride with the gas can mounted for the next hundred miles or so, just to make sure things are secure. Then I'll carry gas and ride Maria till the "low fuel" warning light comes on to see how far I can go before she runs out of gas.
