| ive been told the way to check if u need bigger or smaller is to run ur bike, give it full throttle and then press the killswitch while leaving ur hand on the throttle and killswitch till it dies. then pull out the spark plug and check the color. black/dark brown = rich, white = lean, so if its rich go smaller and if lean go bigger until u hav a good feel for you. hope that helps.
ozminimotos does hav jet kits for reps and genuine.
