MB have these big bore type exhausts gaskets made just for us.

They are suitable for any cast or after market type cylinder with oval exhaust flanges.
 

• Race-Tour
• Tuned standard barrel
• Stage 4 SIL 200
• Mugello
• GT
• Rapido
• Casa Lambretta kits
• Also works on any standard

MB make these gaskets in a modern high temperature fibre type material which is sandwiched around with a copper gasket sheet.

This gasket is considered as a use once then throw away when disasembled.

The main problem is exhaust flanges are not thick enough and distort, so as this gasket can be crushed it will seal a warped flange where as a copper/alloy gaskets will not seal.

These are perfectly good to use on BGM Clubmans with the thicker flanges.
Note these are designed for a perfect fit with BGM Race-Tour cylinders with the extra 2 studs but are perfectly interchangeable with any 2 stud cylinder.
