Thanks guys, much appreciated.
We've ordered a set from 'off the road' and will get them sent out ahead of us. It's just weeping so will hopefully make it up to Nepal where we can replace with the new ones.
Woottonboy, I haven't noticed any tyre wear at all and only noticed the leak higher up on the fork leg as none is dripping down so...
FYI, our bikes have been, this leak aside, absolutely faultless on this trip, despite having been put through some pretty horrendous conditions, in fact, of all the overlanders (on hondas, BM's KTMs etc) we've bumped into we're the only ones to have not been delayed by any sort of mechanical or electrical problem. We really can't speak highly enough about the XT, and more than a few people have expressed admiration or jealousy! It really is the ideal overlanding machine!
We've got plenty of photos if anyone's bored at work.... just click
