There should be two small philips screws on each side of the bezel. Remove those screws, then turn the bezel slightly counter-clockwise (if you're facing the front of the bike) and if should pop loose and pull out.

If your bike is like my M95 Boulevard then when you turn the key to the right and remove the key the park lights will stay on. This will flatten the battery in quick time.
So if you turn the key to the left and remove the key this will cut power to both the engine and the lights.
If this isn't the problem take it to your dealer and see if there is a fault.

To replace the battery:

1- remove the rear (passenger) seat by removing the single bolt behind it. Remove the seat by lifting it up and back

2- Remove the front (driver's) seat). Remove the two bolts behind it and remove the seat by lifting it up and back.

3- Removing the seats will give you access to the battery under the driver's seat.

4- Carefully remove the positive and negative battery cables from the battery, then lift the battery straight up.

5- Place the new battery in the bike

6- Replace the cables, red is positive (+), black is negative (-)

7- replace the seats, and you should be good to go!

Eric,
Purchasing a bike is a personal thing. Depends on factors such as why you want the bike, what you want to use it for etc. Best advice I could give is go out and search for it, you will jnow when its the right one

There are two seat bolts under the seat that must be removed. Obviously, if the underside of the fender is covered in mud, you'll have to clean it first. A metric socket works best to remove the bolts.

After removal of the seat bolts, lift the back of the seat, then pull straight back; a plastic flange on the front of the seat hooks under the tank, and so you have to pull it backwards to remove it.

With the seat off, removing the battery is pretty easy. A rubber strap holds the battery down; unhook and remove it. Unscrew the lead wires and unhook them (negative first), then pull the battery out.

Install a replacement battery by reversing these steps. Yamaha recommends charging a new battery before installing it.
