Don't mention them you will get BigVee all excitedas for fretting of baldrocks, complete or partial, I would suggest lycra undershorts when running![]()

It's all well and good trying to analyse exactly what causes and where exactly how they fail, oiling would just be an added precautionary measure to slow down the corrosion process which then also weakens the spring so therefore it breaks. When someone like Roger says to do this as one of the means to prevent failure, it is wise to take his word for it as there are not many people with as much experience and knowledge with these bikes.
But as has been previously mentioned the best solution is to either do a stop mod on them or take them out completely and fit manuals. At the end of the day they do fail as has been proven on many occasions.
