Looks like you'd get more clearance if you'd sit the wheel a bit further back in the dropouts (i.e. so the tyre sits where the chainstay indents are). Maybe add a chain link or two and pull it back?
Yes, I need to have a mess about with it. I think need to get a narrower chain as the current chain keeps catching the inside of the bashguard which is really annoying, so will try pulling it back when I replace the chain. There's definitely scope for more clearance.
