Hi Steve-o,
That's a nice bike, Congrats!
The ebay CDs that I have tried so far have been scans of Yamaha's (or others) own workshop manuals, sometimes reformatted to prevent copyright issues. Make sure it is actually a 'Service Manual', and not just a 'Parts List' which only tells you what parts make up your bike and nothing about what to do with them!
The original manuals, as I'm sure you know, cost quite a bit more and even the Haynes and Clymer service manuals cost several times more than the ebay copies, so its not a big investment, but as always, ' Buyer Beware' applies.
BTW, what is a 'nemby'? I'm familiar with 'newbie'. Possibly an acronym for NEw MemBer?
Keep the rubber side down!
