basically, I want to look inside it and have a poke about and do the usual... clean it out, put new lube/grease in it and may give the spring a bit of a stretch. But the problem is, err how do I do that? Its a king classic if thats any help? Could anyone point me in the direction, oh and ive done a bit of googleing and found you mite need a king tool, but they seem to be a bit pricey... cheaper option?
