Description

Secure the valve spring retainer during a CN250/172MM engine rebuild with these Universal Parts valve keepers. The two matching metal halves shown lock around the valve stem, making them the small but essential pieces to check when refreshing the valvetrain on a compatible liquid-cooled 250cc four-stroke engine.

Key Features

  • Valvetrain repair: Keeper halves seat at the valve stem to hold the spring retainer in place.
  • Two-piece shape: Product photos show the halves together and separated so you can compare their profile with your originals.
  • Engine-based application: For compatible CN250/172MM-family liquid-cooled 250cc four-stroke engines.
