Engine wise it's basically the same, but thats as far as it goes. I also found that website "www.repairmanual.co.nz" I think it was.
I actually contacted them and heres a snippet of the email.
The manual you ask for is only available in Japanese. We may be producing a full English manual in the future. We will put you on the mailing list to keep you informed. In the meantime you may like to request a section via www.repairmanual.co.nz We will then translate and email you once the material is complete. There may also be sections available for instant download already.
Entire translated manual would be good, I have the jap version, and am lucky that my girlfriend can translate for me, but that still takes time.
