I test drove one and liked it but did notice that sometimes it shifted smoothly, sometimes I thought I could actually feel the gears engaging and sometimes it made a satisfying agricultural clunk as it engaged. Is this typical? I kept it under 4000 rpms so that may have had an influence. Also I noticed in the most recent MOA magazine that maybe the wheels are prone to failure - anyone else experience this? Any idea how widespread that may be? And lastly there seems to be a weep hole issue. Is this a gremlin plagued model?
