During the summers of 2005 and 2006 the Bullets became the first professional basketball club from Britain to tour China competing against Chinese Basketball Association clubs during the 'UK/China Basketball Friendship Tour'. Over the two summers Harker led the Bullets to 13 wins and 11 losses. Harker scored a professional career high of 44 points versus the Shandong Lions in 2006. Harker left Birmingham prior to the 2006 season after the franchise was forced into liquidation- after a two year arena rental dispute with the City of Birmingham. After a strong season and summer the Canadian Senior Men's National Team invited Harker to their training camp.
