Hi
Carried out this mod using early 2009 shock but instead of drilling both mounts to 12mm, I followed another method spotted elsewhere which retains 10mm bolts using custom bearing sleeves, OD 12mm ID 10MM, fitted to fazer mount points. I fitted 110NM spring to shock, set Compression adjusters to BMW "Comfort" positions and Rebound to 7, so far. At same time fitted r6 5EB forks, resprung also. Bike handles great just harsh over sharp bumps. Came back after latest run found what feels like top mount worn, lifted rear found a lot of play, I now have correct spacers for top mount to fit but it may well be BMW shock mount may be extremely worn - if necessary how do you remove the top bushes, any help would be much appreciated.
