Trailblazer125 Posted December 18, 2015 Share Posted December 18, 2015 Hi I am looking at buying a dt 125 r 2003 and was wondering if I have to change the main jet in the carb if I'm de-restricting by earthing the servo and getting a dep expansion pipe and silencer ?? If so what jet size would I need ?? Thanks in advance Link to comment Share on other sites More sharing options...
