I have noticed some slop in mine but its never been an issue. I know that with the 1500 drive line is a worry but these bikes are completely different.
The construction is there are no bushings like the 1500, the bushing on these is actually part of the driveshaft. The driveshaft consists of 2 shafts one inserted inside the other and rubber holds them together. Similar construction to a engine damper with the pressed in rubber. I also doubt if you have any problem with the gears so you should be good to go. The driveshaft can be bought used for 40.00 cheaper than the bushings for the 1500
Good news! Thanks
