Other than the 2 cycle oil that goes in the tank what other oils or fluids do I need to add? If you are sitting on the bike on the seft side below the carb there is a bolt with a gasket on it and a spring under it. I took out the bolt and there appears to be oil or fluid there. How much and white tipe do I put in? On the right side next to the kick start there is a plastic cap with a dip stick on it. This compartment is empty. What type or weight of oil or fluid do I put in?

Thanks for the info. After putting it in gear the oil light went off. The motor seems loud to me like piston slop or the rod on the crank being noisy. There is a plastic cap next to the kick start and the chamber is empty. Is this for the transmission? What kind of fluid or weight of oil do I use. There is a bolt wwith a gasket on it and a spring underneath the carb on the left side if you are on the bike. What is this? There appears to be oil or fluid here. Is this something I need to oil?

Ijust bought a 1982 Yamaha 100 enduro and know nothing about bikes. The bike runs great but the red oil light under the spedo is on when the bike runs and I do not want to damage the engine. The oil tank is full how do I know if it is a bad sensor or if the oil injector is not working? Can I add oil to the gas tank and pull the small line off the carb from the injector to see if oil runs while the bike runs? Is ther something I can do to know if the injector pump is working?
