Right. There's a lot of just plain common sense about Enfields.
Just an aside: The hardest part (the ONLY hard part) of a filter change on my AVL (because of hand and wrist (and everywhere else) pain) is holding that damn cap in against the spring pressure to get the washer and nut on. That spring is ridiculously stiff (to me).
There will come a day......
"common sense"?!?
I threw all claims to common sense out the window the day I bought this bike.
But yeah, a little hylomar on the threads of the stud, like Tom said works fine. It stays tacky so it's reversable. A little dab'll do ya.
