067927C GASKET SET 500,600,650 TWINS

Norton 500 600 650 Twins Gasket Set – Copper (Part 067927C)

If you’re working on a pre-Commando Norton twin — a 500, 600, or 650 — this is the gasket set to have on the bench. The Norton 500 600 650 twins gasket set, part number 067927C, covers the full range of Norton parallel twin engines from those three displacements, giving you a single copper gasket kit that handles whatever rebuild you’re tackling. Whether you’re freshening a 500cc club racer, resealing a 600 tourer, or rebuilding a 650 for the road, this set has you covered.

These engines are the foundation of the Norton twin legacy — smooth, torquey, and built to last when maintained properly. A quality gasket set is one of the most important investments you can make in a rebuild. Copper gaskets in particular are the preferred choice for serious restorers: they conform to mating surfaces, seal reliably under real-world heat cycling, and don’t degrade the way composite gaskets can over decades of sitting. Get it right the first time and you won’t be pulling the engine apart again next season.

This kit includes all the gaskets you need for a complete engine reseal — head gasket, base gasket, rocker covers, timing cover, primary cover, and all the ancillary seals that add up to a leak-free, oil-tight engine. Stop hunting for individual pieces from multiple suppliers and get everything in one go.
