I can send you one that has been doing the rounds for quite a few years, not for the Roadster but better than a kick in the arse.
e-mail me at fifer642@cox.net if youwant it.
just tried to send the 24mb PDF file to couple of members but couldn't, it bounced of my own antivirus so I went and found the source I originally got it from and here it is http://www.cuppabella.com/Service_Manual_R3S_C_T.pdf
Cheers

Actually All the Thanks should go to "Bishop" from the .com site as he was the one created the link in the first place unfortunately it does not have Roadster in it but there would only be a couple of things lacking such as the ABS as this manual was a 2007 publication
