Can anybody help with the above?
The cap is absolutely solid and all I want to do is check the oil level.
I have found a German Company - Thiel Motorsport - who make a polyamide socket that fits over the standard 4 lug cap - has anybody ever dealt with them? This item along with a number of other bespoke Norton 961 accessories are listed with prices on their website but no apparent ordering system.
Is anything equivalent available from the UK?
