The battery hanger tension ,the condition of the components, the reduction of the inertia,the surface of the contact between the plunger and the cam plate, these are all discussed ad infinitum and I and many others understand the problems and we all have that very grimy page in our Richardson!
But the basic problem remains it is a hitt or miss situation not up to the level of dependability of the rest of the bike I venture to say even the Albion box change is more dependable.
Tomo is one of the few guys who have tried to tackle the root of the problem but I see few other attempts in our archives. Sometimes you are lucky but it shouldn't be like that we all know it comes back to bite us in the b*m, or perhaps I am the only one?
