Lambretta Big Bore Fibre Type Oval Exhaust Gasket
These big bore type exhausts gaskets are made in the UK in a modern fibre type material. The solid brass ones can be prone to leaking. (The main problem is exhaust flanges are not thick enough and distort. This gasket can be crushed and it will seal a warped flange where as a copper gasket will not seal.)
This gasket is considered as a use and throw away item, ie; use once although it can be used again if not damaged.
These are suitable for any cast type cylinder with oval exhaust flange.

These are perfectly good to use on MBgm Clubmans with the thicker flanges. Note these are designed for a perfect fit with MBgm Race-Tour cylinders with the extra 2 studs but are perfect interchangeable with any 2 stud cylinder.
If a stud or nut comes loose these will eventually break.......... Always use decent studs, nuts and washers and keep them tight.
