remove front plastic and tank, remove rocker covers and cam sprocket cover. Take and get timing mark to TDC, with the line on cam sprocket facing up. Remove cam chain tensioner. While holding the flange under the bolt on yor timing stator cover, loosen bolt on cam sprocket. Remove cam sprocket -don't drop chain down into block - put a wire tie through it. There is a holding bracket for your cam visible now -remove it. Put cam sprocket bolt back in some and pull -cam should come right out.
Don't know about the inner bearing -never had to pull one -shouldn't be to difficult to figure out as the outer one slides right out.
