Bad battery

Don't rely on on whether the bike will start at a gas station to determine if the charging system is working. Get the multimeter out and do a proper test. Should be getting about 14.5 volts @ around 3K RPM. It's too easy of a test to to just skip. If it is charging then start looking for something else. Was the new battery properly charged to begin with? Loose battery connection? I suppose the GPS could be too much but you said that it was dying last november, so I would suspect something else. P.S. you need a properly charged battery to get an accurate reading for the charging test.

Fuse for the headlights for 650 BMW 2008

On a 2008 BMW 650i, the fuse for the headlights is located in the fuse box under the hood. The specific fuse you need is Fuse #61, which is a 20-amp fuse located in the third row of fuses from the top. To access the fuse box, open the hood and locate the black plastic cover on the right side of the engine bay. There should be a diagram on the underside of the cover showing the layout of the fuses. Once you've found the correct fuse, you can use a fuse puller or a pair of needle-nose pliers to remove it from the fuse box. It's always a good idea to check the owner's manual for your specific vehicle to get the most accurate and up-to-date information on the location and function of the various fuses.

My 2003 BMW R1150RT won't start after it overheated, what would the problem be?

It depends on how hot it got and for how long? Holes in the pistons under the spark plugs. Burnt Exhaust Valves. Stuck Valves. First thing to do is to remove and visually inspect the spark plugs and then test for compression. Interesting reviews and on mentions burnt valves. https://www.motorcyclenews.com/bike-reviews/bmw/r1150rt/2001/ ..
