i just bought this off ebay. it has the adapter plate and oil filter cover with oil line ports and a bunch of other parts im going to resell on ebay http://cgi.ebay.com/ebaymotors/YAMAHA-350-BIG-BEAR-4X4-ATV-ENGINE-PARTS-LOT_W0QQitemZ4570256260QQcategoryZ43977QQcm dZViewItem
the link doesnt work but i dont know how to fix it so just copy and paste. i won it for 40 bucks just the parts in there that i wanted would have cost me over 100 bucks. im stoked
