Hi Brian.

I will start by telling you the same thing that the vast majority get told; Get the repair manual.  It has references and specs that you will need.

The bike is a 2-stroke, so it uses a fuel/oil mixture of approximately 50:1 (fuel:oil).  If that mix is oil rich, then it would foul the plug.  The same if it is fuel rich as well.  Make sure that the fuel:oil mixture is correct.

Also follow the troubleshooting guide in the repair manual if you still have a problem, in case there is anything that I missed.

Good luck and ride safe.
