Remove the center console and see what you can see.

Unhook the connection under the gas tank. Remove the pins from the elelectrical connection for the fuel gauge. Pull the gauge up. It is held in place with a piece of plastic that surrounds the gauge housing. Good luck!

Oil tank remove and replace the oil tank

Check for clogged jets. Also remove the air filter and look into the carb while working the throttle. You should see gas squirting into the carb from the accellator pump. If not, the accellator pump orifice is clogged. Also check the filter on top of the petcock inside the tank.

The oil drain us usually a hose with a plug in it that is held by a clip on the frame. It us usually on the right hand side of the bike just behind and underneath the transmission side cover. Loosen the clamp and pull the plug out. The oil will run out of the tank. Replace plug and add new oil to the tank.
