tricycling admitted "I havnt greased them properly (WD-40) is that bad?"

did they click *before* you used WD-40?

I'm famously mechanicly challenged so don't quote me.... but I would not use WD-40 (for general pupose and cars) lube on a bike. I do use a little bit of WD-40 on a shop rag to loosen dirt and grime before cleaning. But then I clean and then lube the bike using a bike specific products.

"A clean bike is a happy bike" so a proper cleaning and lube might do the trick.
