Hi! I've been looking without luck for an Owners /Service Manual and/or CD for my 2008 JIANSHE-YAHAMA JS250-8 SPORT QUAD (YFZ450 frame and Plastics XT225 229cc engine) for about a year!! I do have the retail information but that company isn't around!! I have their web page advertising for the quad. Thanks for any help you can give me!!! Matt
