Which Service Manual should I buy?

[HumbleNewRider]

Thanks for posting the scanned service manual. It has been very helpful. I just bought a 2008 GZ (with 588 miles) and used the manual to perform the 600 mile break-in service.

However, I would like to buy a good service manual, as some of the photos / images of the scanned manual are hard for me to see the detail. When I find used copies on eBay, etc., they never specify which year they cover, but there are different publication dates and different editions. I'm presuming Suzuki released new editions due to changes in the motorcycle. The different service manuals have different part numbers.

While searching this website, I did read that there have only been slight change to the combustion chamber design in 04. The latest edition of the service manual I've seen on eBay is the 4th Edition published 2004. Does anyone know if that was the last edition published by Suzuki?

Does anyone have a suggestion for how to decide when edition / part number I should look for when buying a manual?

And, are there non-Suzuki service manuals that are better? (I've not been a fan of Haynes repair manuals for cars. I've never seen or used a Clymer repair manual. The "Cyclepedia" service manuals look like they might be really good (nice color photographs), but even with a lifetime subscription --- I hate being dependent on a company staying in business.

Your thoughts are appreciated....
