Since his youth, Franak has been involved in the opposition movement to current Belarusian president Alexander Lukashenko. He is a former pupil of the Belarusian Humanities Lyceum and was formerly chairman of the BPF Youth, the youth wing of the Belarusian Popular Front, succeeded on October 10, 2009 by Andrei Krečka.
It has been reported that on 16 January 2009, Franak was forcibly conscripted into the Armed Forces of Belarus by the authorities, despite having been found medically unfit. Several other youth activists, such as Ivan Shyla, were also drafted. In the course of his training, it is alleged that he has been subjected to harassment by senior military figures in order to make him speak Russian rather than Belarusian, although both are legal for use in the military. As of July 2009, he was stationed in the air defence unit 48694 in Mozyr, Homiel Voblast. On April 14, 2010 Viachorka was released from army because of health problems. During his military service Franak participated as a candidate in local elections to Mazyr City Council, but didn't get in.
Since 2011 Franak Viachorka is a member of organisation committee and International Secretary of a new Popular-Democratic Party "Belarusian Movement" in opposition to regime of Alaksandr Lukashenka.
Since 2008 Franak is working at BELSAT TV as a coordinator of promotion in Belarus.
Franak is a producer of several musical rock-projects.
