Had a look today and the brake caliper is in place fine with no movement.
Banging got louder on my way to work this morning so managed to get it into a yamaha dealership on my way home. They were kind enough to stay open late for me to check it over for free.
They checked over the bike and said my chain was to tight however i had adjust it this morning before work so its tightening up somehow. They reckon its the chain and sprockets thats gone bad. They did say it was really clean and shouldn't be gone with only 6k miles on it.
They re adjusted my chain again which made no difference at all for me but the guy there tried it and it was less bad for him than the first test ride he had on it.

They reckon its something to do with the chain and sprocket cant get it in till Saturday so ill update this thread then to let you know what the issue is. That is if they find it.
