I removed mine cause they were causing the bike to die at innopportune times...Really annoying...Turns out my throttle was sticking and the TORS were doing their job. The next time I rode after removing them it stuck wide open riding a wheelie across the face of a big dune at Winchester Bay, OR... Cartwheeled me and the bike.... Thank goodness for tethers..... I still don't run em but...........
