Fuel Tank Removal
The Fuel Tank is removed in order to perform a number of procedures including air filter element inspection.
It is not essential to remove the battery but it is always safer to avoid the possibility of causing an electrical spark which could ignite spilt fuel or fuel vapors. Removing the battery negative lead is sometimes suggested as a means of disabling the battery without removing it completely. Actually this is more dangerous that just leaving the battery in and the bike with both negative and positive poles connected to their respective leads. A loose negative cable can easily get bumped or arch to a ground on the frame causing a spark. If the negative cable is removed, the lead should then be wrapped in electrical tape to prevent accidental contact in the presence of gasoline.
The flow of fuel from the fuel pump is high pressure and could easily cause a line to blow off and cause a serious fire hazard if the line is not properly connected. Always double check that the fuel feed hose coupling is securely attached to the fuel delivery pipe on the fuel pump. You must feel the catch click. Pull on the connection three or more times to be sure the coupling is locked.
Having the gas tank completely empty isn’t necessary but the fuel gauge should be on E or not much more so that the tank is light enough to handle without added risk of dropping the tank.
Tools:
6mm hex tool
4mm hex tool
rag
string
Removal
Empty as much fuel from the fuel tank as possible. It is safest to remove the battery when working around gasoline drips and fumes. Remove the two bolts that fasten the pilot seat with a 6mm hex tool.
1. Use a 4mm hex tool to remove the two screws and washers at the front of the fuel tank.
2. Remove the hump and take the fuel tank prop stay out of the storage compartment. Insert the prop stay into the steering stem and the other through one of the screw holes at the front of the fuel tank.
3. Disconnect the fuel pump leads.
4. Place a rag under the fuel pump. Disconnect the fuel feed hose from the small pipe on the fuel pump. A small amount of fuel may drip out.
The fuel feed hose is disconnected by squeezing the white tabs and pulling the black connector off of the pipe.
5. Tie the tank to an overhead structure with string so the the tank is lifted to its full height.
6. Push the surge hose and drain hose off of the nipples at he lower right bottom corner of the fuel tank. A small amount of fuel may drip out.
7. Rest the tank back in its lowest position. Use a 4mm hex tool to remove the 4 fuel tank bracket bolts from the back of the fuel tank.
You may wrap the fuel pipe and nipples on the fuel tank with plastic secured with a rubber band. This will stop any drips if the tank will be stored off of the bike for some time.
Installation
8. Place the fuel tank on its frame mounts. Use a 4mm hex tool to tighten the four fuel tank bracket bolts.
9. Tie the tank in its highest position. Connect the surge hose and drain hose.
10. Support the tank with the prop stay. Line up the tabs of the white plastic collar on the fuel delivery pipe with the mating slots in the coupler on the fuel feed hose. Press the collar and coupler together until you hear a click. BE CERTAN THAT THE FUEL FEED HOSE IS SECURELY CONNECTED BEFORE STARTING THE ENGINE!
Connect the fuel pump wire leads. Remove the rag fro under the fuel feed hose coupler.
11. Lower the fuel tank. Use a 4mm hex tool to tighten the two bolts at the front of the tank just snug enough to compress the rubber pads.
