ok guys ive noticed something. When i spin the back *wheel* foward the front wheels spin to. so does the clutch bell. is this normal? i thought when you spun both back wheels foward this is ment to happen?...i took it out for a spin and its not as bad as it was but still losen abit of power? [&:] im so confused on what it could be...could my slipper pad be glazed? so i would need to roughten it up? or maybe because ive got a new exhaust my slipper clutch setting would need to be tighter?
