Hi Lee,
the rocker cover gasket for the CSR needs to have two additional “ears” to tighten the secondary air system (SAS).
The SAS is located on top of the rocker cover, right above the exhaust camshaft.
Most of the available gasket sets include the matching CSR cover gasket. Using that with a B you can see the “ears” standing off unused and can be cut off afterwards.
Gasket sets will cost around 50,- to 60,- Euros over here in Germany, but no sealing rings included !
You may want to change the sealing ring of the switch lever axle as these tend to be untighten and are under the upper oil level.
Cheers, Michael
