The holes on the swing arm (zxr400 L1) for my bobbins to fit into are mashed up. i re-tapped them with a m12x1.75 but the bobbin wouldnt fit :smt013

What is the thread and increment size on the swing arm bobbin bit. m12x1.5? gotta buy helcoils.

cheers

Bobbins are M12 1.25 but if you have already tapped at 1.75 then probably cheaper to source an M12 1.75 bolt than helicoilng
