2012 250cc D-tracker
Hi
I would like to add a FMF Q4 to my 250cc D-Tracker (fuel injected) but my understanding is to prevent back firing when the throttle is released and to operate correctly I should weld on a bung to fit the oxygen sensor to the FMF slip on exhaust, can anyone tell the correct thread required for the bung?
