duke ii 640

  1. Supermoto
    Hello! New member here... I'd have a couple of questions for 640SM/Duke 640 owners. I see that the BST "slide" holes can be enlarged to make the carburator response faster... is it worth the effort? Another question: my bike still has the original air filter... is it worth the effort of cutting...
