First of all, I am new to this site as well as riding. I have owned my 2006 M50 for about 6 months. Riding this bike is fun but not knowing how much fuel I have is sometimes nerve racking. I would like some advice on the fuel gauge. I am either thinking of purchasing an after market device and installing that or going with a speedometer from a 2007 M50 since it has a fuel gauge built into it. Could you guys help me with this delimma since I have no clue and am mechanically challenged as well. Thanks in advance for taking the time to read this and point me in the right direction.
