XR 650L 53 000kms. What do I need to look out for?

[East Coast Outlaw]

Hi all,

My XR650L has just hit 53000kms. I am planning a month long ride through SA, Nam and Bots in December. Currently, there are no issues with the bike and it goes like a bomb.I dont have any big trips planned between now and December - maybe the odd 2 nighter. However, in December we plan on doing around 6000kms. What should I be looking to change/service, other than the normal things, come our pre-trip maintenance?

Any help will be appreciated.

All I know, is check the frame for cracks regularly near stress raises (welded joints) and some had an issue with loose exhaust valve seats.  other than that sound.
