Service history - value?

[mistergixer]

I've got my lovely Gixer up for sale, whilst digging out my V5, MOT etc i've discovered that i've mislaid/lost the service history for the bike.
The bike has 5.5K miles on it, is a 2005 model, and is in tip-top condition (although due a service), so the question is - what value would you put on service history?
Bike is up for £4500 ono, i don't think that's unreasonable, but that was when i had the history for it. £4250? £4K?
Your thoughts, gentlemen please.

Did you get it serviced at the same dealers everytime?

Might have a computer back up if you did which they could print off as proof, thats what i did with my scooter when i sold it 2 years ago.

Honestly, espically with that milage, I wouldn't say the bike's worth any less without the service history, just might make it a little less appealing.
