May be teaching granny to suck eggs here, but having purchased Kouba Links from the USA I set about fitting said items and to my horror found that after 11 years of neglect by the previous owner and incompetence by the M/Cycle shop who serviced said bike, both the bushes needed to refit the new links were shagged beyond recognition. Call my local friendly BMW dealer only to be told they are no longer available from BMW, Now I ask you, this is an 11 year old machine FFS, ordered s/hand usable bushes from Motorworks, went back to the bike to clean everything up only to notice the bottom bolt that secures the linkage to the frame had snapped, so my couple of hours quick fix now turned into a complete nightmare, found a complete linkage for a reasonable figure, collected it from Stoke on Trent whilst out working, got it home and all the fekin rollers fell out when I removed the bushes. Said bushes were in good order so I managed to complete the job at 8-30 pm. Motorworks postage took 3 days to arrive after ordering. Bike had done 70,000 hard neglected and unloved miles, but I recommend a look at these if you have GS or Dakar F650. Would post pics but its witchcraft to me!
