there should be a fuel level relay in the top of the gas tank. i havent been able to find an image yet, but in a car, it is located within the fuel tank, mounted to the top- usually inside the fuel filter assembly.

try a new spark plug or check the Electricals on the bike from the battery to the engine i dont know how to but i would check them

Tail light or instrument panel back light? The tail light should be straight forward remove and replace. NEXT - Disconnect the battery! The instrument panel, remove the panel, the gauges will probably have a mount or cover, remove it and the bulbs should be rubber plugs in the bottom of the gauges.

It looks like the lens screws are under the fender, but you might have to remove the assembly. Two nuts attach it to the rear fender. Use WD40 to loosen, and wash area to remove mud and dirt. Hope that helps.

broken rings or head gasket.

Don't worry about limit if the disc is not warped or gouged, just replace the pads and be done with it. have fun ridin bro!

contact a dealer for manual or go on line and look for Yamaha work shop manuals for you machine.

Check your battery voltage ... then check the start solenoid for proper operation.

try ebay or a motorcycle salvage

If you took out the battery & then you have a problem it means that the speedo (I am assuming that it's digital) runs off the battery & not off the lighting coil.

Turn the ignition on and hold the pass light button in when it says either endr or ntrd depending on whether your bike is an enduro (off road) or the other one (don't know the name).

Try unplug its harness connector behind it and use compressed air to clean it. before you plug it back on put a little of lithium grease in the connector to prevent this to happen again.If the problem persists then you should see a dealer cause the water penetrated inside the cluster.

Won't build torque or rpm.Steps:

1. Clean your air cleaner and spray it with light filter oil.
2. Check your exhaust pipe make sure it's not plugged or restricted
3. Gear ratio - too many teeth on primary sprocket?
4. Install a new or clean spark plug for color testing. Want a cocoa brown.
5. Jetting - Needle Valve - Raise the cir-clip a notch at a time lowering the needle into the pilot jet. Mostly effects the mid-range 35 - 60 mph.
6. Jetting - Main Jet (should be OK) if it has been changed/increased to a larger orifice you may want to go back to stock. This usually effects speeds when the wire is tight and your running is WFO. Wound Flat Out.

Worse case scenario:If this bike has a lot of hours on it you may want to freshen up the top end. Re-ringing the piston and honing the cylinder head with a good cross hatch pattern works wonders to get power back. We used to do this every couple of races. If the cylinder is slightly oval shaped it needs a bore and next over piston and rings. (Most frequently a problem with 2 strokes) Hope this helps and keep us in the loop. TF

Sounds like your bike is running to rich. Find and remove your air cleaner element, if it is clogged that is your problem. Easy way to tell is to get a torch and hold it behind your filter if you can't see the light or it is very subdued your filter needs to either be cleaned or replaced.
If it isn't your element then your carb might be fouled or your leads may be breaking down
