    Two Strokes
    my first post :) I have a 2018 TPI 250 2T KTM and every two or three hours my sparkplug fails... the bike will not start only when I replace the spark plug. did anyone encounter this with his/her TPI? what could be the possible causes what could be the possible solutions... thank you very...
