Hi Chris,

The clutch side of the swingarm bolt is a socket (not sure on the size) and the other side is a 14mm allen key. You hold one still whilst undoing the other.

Don't be under any illusion that it'll be easy with 'a decent wrench'.

Plenty of 748/9** owners/members will attest that this can be a ba*t*rd of a job if it's never been undone before (i.e. not loosened up and regreased etc).

Once you have the clutch-side nut off, it is (or should I say "should be") a simple task of sliding the swingarm bolt (SA bolt here on) out by 'tapping' it from the clutch side using an appropriately sized piece of tubular metal or bar (i.e. a 'drift'). Ideally you could get the right sized socket but get it in a 'deep socket' format where the socket is about 3 inches long. That way you could undo the nut on the SA bolt about 2 turns leaving it inside the thread of the SA bolt and then remove your socket wrench and then hammer on the end of socket itself enough to budge/free the SA bolt.

Instead and more often than not, it's a casing of braying absolute f**k out of your bike as the SA bolt is jammed solid and doesn't budge under even the most extreme persuasion....trust me... I and many others have been there and is why I say be carefull not to damage the threads on the clutch-side end of the bar or indeed, flare the ends of the bar itself as you hammer on it.

HTH even further but shout if you need any more.
