Errol used to make them, send yours in and he'd modify it to have a removable cover. I think it cost AUD$120.




Kiri1 not sure what is available in South Africa but I think it would be easy to make your own operable timing case cover. But you'd need a spare to experiment on first.

Here is a Kameari timing sprocket. You can also drill the stock one to suit, depends what cam you run I suppose.
