Base Manual For 2002 ZZR250 - Wanted

Ok so im new on here just recently bought a 2002 ZZR250 am going for my license on the 18th may 
Don't know to much about bikes so took my mate who had a 92 ZZR250 for his learner bike to have a look at it and took it for a ride said its all fine i just need to replace the Cam Chain Tensioner, i bought one and i have searched on the forums and found the Service supplement manual for my bike here http://www.eightballmedia.com.au/zzr250 ... lement.rar but when i look up the cam chain tensioner it says refer to base manual... From what i have read it uses the base manual for a gpx250? maybe? As from what i have read they have the same engine. Can anyone point me in the right direction of the base manual? Im just not 100% exactly which one i need Preferably as a PDF download? Bit tight on cash after buying the bike lol
Thanks in advance!
