ok, this could be quite simple... or complicated. Check your slipper to see if that is setup the way it should be. NEXT, watch the clutch bell and see if it rotates, if that does, then your spur should be rotating. Then ur tranny will be workin and if that is so... look at your drive shafts, they should be turning too. It kind of sounds like a slipper issue here. Tighten it up and it should rip!
