I have a Yamaha KT100 and was wondering about oil changes or whatever since i just got it and i wanna make sure i dont ruining it by running it without oil.From what i can see its like a weed wacker and you actually mix oil into the gas. Is this correct or am I wrong? The guy i got it from didnt seem to knowledgeable and i dont think he was mixing oil into the gas. If it jst runs on regular gas what could happen?

Running a two stroke with no oil in the gas is like running a four stroke with no oil in the crankcase.

Your engine does not use oil in the crankcase like a 4-stroke engine, 2-stroke engines like yours get their lower end get lubricated by the oil you add to the gasoline.
Your KT100 needs 8 ounces of Premix oil added to a gallon of premium grade gasoline. (that's a 16 to 1 mix ratio) Then always shake the gas can a bit to mix it up well before pouring into your gas tank.
Don't use regular engine oil or a cheap brand of Premix oil, a popular choice with guys that race KT100 engines is Yamalube 2R, its available at any Yamaha motorcycle dealer.
If your town doesnt have a Yamaha dealer, this link has some good info about other brands of premix oil that are reported to work well with KT100 engines: https://karting.4cycle.com/showthread.php?22717-Yamaha-KT100s-and-Oil-Castrol-Edge
