i have been reading up on the threads ppl have been sending in on vibration...i have a vibration when im rippin my z-400 im kinda thinkin its my crank bearings...my question is...is there a way to check and see if its teh crank bearings before i rip it all apart...anyother ways around it like tryin to move the shaft the fly wheel is on to check to see if there shot???

Yeah thats a good way. My friend felt slop that way in his 250r and he tore it apart and the main bearings were shot.. He had to buy a case as they don't sell main bearings for the 250r anymore..
