what do you mean your piston froze up? i have a 86 also.

 

Squirt a little MArvel mystery oil in through the spark plug hole. just don;t use a lot. Let the thing sit overnight. Next day, put the quad in gear and gently rock it back and forth. Don;t force it!!

Depending on how you siezed it, you may be looking at a rebuild...
