Right guys, bike is in a few bits this week and noticed how very slack my chain is, the lowers are off and the Centre stand is fouling the chain, not sure if I tighten it whether it will stop this but the chain needs sorting. I have read a few posts/threads and just need a few pointers really(

).
1) Don't have the correct size torque wrench (but yes I have got one

) to do the rear spindle, can it be done without?
2) What needs adjusting and unsrewing and how?
Pretty much, can someone do me a walkthrough please if they have time? Or better so if someone fancies a trip up to Northampton tonight, I can provide coffee and biscuits and I'll even get you the takeaway of your choice... Haynes is out of the question as I have left it at my Nan's
