Dear all, what spanner do you use for the spark plug? Is there one who can do this without taking the fuel tank away, together with some head fins? Any modern substitute?
Thank you – Micha.

I use the original toolbox spanner, and still have my fins
Well, most of them

Henk has one for sale in the "parts for sale" section

Or a standard 13/16" AF cranked ring spanner is correct. Ron

I use one of those with the other end cut off so it fits the toolbox ...Ian
