Hello All,
Just would like to pass on some advice if you are looking at doing the bearing mod to the cush drive, from a bad & expensive experience on the weekend that destroyed my swing arm & hub after the alloy casting broke away allowing the hub to move to the outside chewing into the swing arm & hub.
My bike had the double bearing mod (2 x 6304 2rs) that machines 15 mm out of you hub & 15 mm off the spacer leaving a small amount of alloy that stops the hub moving sideways. the better way to go
may have been to use the wide alternative of the same bearing (62304-2RS) & machine out only 6mm giving a lot more support. another alternative may be to install a internal retainer clip to take some of the load if there is enough room, I have not had a chance to look at it yet but will keep up to date with how I go.
This did happen while riding in steep country with other bikes, lots of erosion mounds, and going hard with good traction, I have tried to attach some photos but no luck as yet ??
