hi folks,just saw this post.the" spragodeptomey" is a pretty simple matter.if doing it for the first time you will need to order part# dc-4127[3c] from stieber sprag. i ordered mine from allied bearing supply in ft smith ar. or fleck bearing will have them allso allthough fleck in ft smith didnt seam to know how to read mics...anyway that is the correct part # to replace the bearing only.if after several thousands miles you need to replace it again,then you will need to purchase the kit from your dealer and replace the gears as well.bearing cost was about 80 dallors,the whole kit is about 400 i think. do not wast your time and money trying to purchase one from india.it taks forever for them to respond to you and then after several emails they still sent me the wrong part cost about 100 dallors,time and money wasted. i sugest that you purchase the clutch center nut #st-25591-4 from your dealer as well this keeps the gears from movung as its replaced. just a tip as far as other things ive noticed about this bike its seems to like cheep things such as cheep gas no achachol cheep plugs i use autolite 63 and cheep airfilter, i use napa #2362 the plugs are like 2.50 ea and the filters 5.55 just good stuff to know if you get stranded somewhere or your cheep like me...stay safe
