Do you guys and gals remove the bearings from the swing arm to re-grease? Or is it o.k. to just clean them out and re-grease. These are the four sets in the swing arm not the linkage. The needles do not come out they are encased with the bearing as a whole piece. Also My linkage didn't have any string cheese in it, did Yamaha quite doing that? Hey here is another. Why are there not sealed bearings in there? You know the maintenance free type. I'm doing this on my new bike I have had for 3 months and finally have about 15 hrs on it. Boy is it ever the truth these suckers need to be tore up and re packed right away. I thought the guys who tore em up before even riding them were just nutters with maintenance. I figured waiting till the break in would be plenty early. I would say that is about as long as you would ever want to go. I already have a little spotting of rust on the end of one of the sleeves. Any way thanks for the input, there seems to be a lot of info on the linkage but nothing much on the swing arm.
