2004 ZX636R questions

Good evening punters,
I do not own a 2004 ZX6R, but one of the locals down here does - he is not a member, so I am asking some questions on his behalf.
Old mate has the opportunity to buy an 04 636. It will be a dedicated track bike.
What is the general opinion of these little jiggers ? Is there anything that he should be on the lookout for ? I think its the first FI model 6, so any tips or traps for newbies would be greatly appreciated
Hang out the dirty laundry, we want any advice warts and all.
cheers
