The kit contains every seal, gasket and O-ring in the engine.

This kit is intended for bikes built before 09/1975, with 16mm diameter pushrod tubes.  If your bike has the later 18mm pushrod tubes, please see ENA37998.

Please note, on some early R90S models dowels were used on the cylinder. Unfortunately there is no gasket produced for these models, so modification to the head gasket is required to suit.
