To sell or not to sell?

I'm almost at the 32000 mile mark now and have had the Pan for over two years. I still love the bike to bits but there's no getting away from the fact that it costs a lot of money to run.

The 16000 mile service cost a fortune and this next one promises to be no different. Added to the fact the clutch needs replacing, it'll be a huge bill.

My preference would be to keep it but with a house requiring major restoration, I may have to make some sacrifices. Now, I still need a bike as I go through the City a lot (free parking and no Congestion Charge) and need to park at airports frequently (again, free on a bike). The question is: Can I justify keeping such an expensive machine indefinitely?
