Setting off on a high milage bike - bad idea?

[Alfie]

Hi.

I currently own a Honda XRV750 Africa twin that has done 46,000 miles. The bike has been ridden hard - lots of offroad and fast on road stuff. The bike has been well maintained with very regular oil and filter changes and valve clearance carried out at the specified intervals and although it users a tiny little bit of oil occasional, the bike runs perfectly.

My question to the board then is would I be foolish setting off on a UK to OZ trip on a bike that has such high mileage? What, if anything is likely to cause problems and what preventative measures can I take, short of a full engine rebuild, to minimise any potential problems once on the road. I have already decided that cam chains and clutch are a must but anything else? Would I be better off simply replacing the engine with a low mileage example (£1000 in the UK)

Any advice would be greatly appreciated.
