Are these gaskets made to specific tolerances?

Yes, Athena uses laser cutting for precise dimensions and applies surface treatments to ensure good sealing, even with minor imperfections on the engine surfaces.

Do I need any special tools to install these gaskets?

While this kit is a direct fit, proper installation requires basic motorcycle engine tools. Always refer to the service manual for your 1983-1984 Yamaha YZ80 for detailed installation procedures.
