Mate that electronic copy of the service manual is all you need, provided your good at interpreting the terse as hell explenation & assumptions made. But it'll do to get you out of most pinches i find.
Pitstop bookshop in Perth may have them, even though i cannot find it in their online listing. I bought a book from them (ordered it at 5am on a tuesday morning as i was on night shift) and they called and apologised at 9:00am their time (midday in Sydney) as i had to wait until Wednesday morning before they could post the book as they'd run out of my book the day before and couldnt ship it on Tuesay, definately what i call customer service. It arrived Thursday morning, incredible!!
If your determined to find an aftermarket manual, in australia look for the zzr250 / gpx250, for the US, ex250 & ninja 250 if thats any use. Oh and ebay is good for these kindsa of things too.
