Gents, I am looking for a pair of water jacket rings for my 1921 2 speeder please. The engine is similar to the pre war ones and has the spark plug on the back of the cylinder barrel. The ones I have have 4 spigots or castellations and since I don’t have the old ones, don’t have any dimensions yet.
Any help genuinely appreciated. I can get them made but folks have stuff in sheds etc.
Thanks, Will. 07531 781196 or willsleddon@yahoo.com
