When I hoist the bike up onto the stand or remove all weight from the rear it makes a bad sound. Kind of a 'your linkage bearings are shot and have free play' sound. Not positive it's coming from the linkage but from the amount of posts this area seems to be problematic in these bikes. 06WR450, have never checked or greased or really paid that much attention to the rear of the bike (unless it's trying to pass me in the air). I'll pull it apart and check, but if the bearings are goners are the bearing replacement kits sold by MSR a good solution? Does Yamaha or any aftermarket company sell a complete rear linkage to just replace it with? Any insights appreciated.
