Long distance/classic reliability trials on C15T

[KernowPete]

I'd like to prepare my C15T (currently in bits) and myself (horribly out of shape) for this years Tamar Trial which is on my birthday in October. It would be great to get any tips on doing this trial on a C15T. I read that someone once cleaned every section on one!
I did this trial about 15 years ago on a KTM 300 and haven't done it since.
I'm intending to get the bike back together over the next month or so, do a bit of greenlaning, head to our local trials practice place regularly and go to the gym.
Bike set up info would be very welcome.
Thanks.
