Hi all,recently bought a trial bike its a 95 gas gas jt350 contact. None of the wiring was connected so ive done my best of what info i could find and got it sparking but the cut out button dosent seem to work,it sparks all the t8me even when it shouldn't, do i need a new button or have i missed something, ive got it wired to the black wire on the cdi and earthed the other wire,any help would be appreciated. thanks.
