In need of replacing the swing arm bearings. I've replaced all kinds of bearings so this question is specific to the ST1300's setup not how to punch out a race as I can do that in my sleep... So as I'm looking at the race there is a thin walled "cap?" behind the race set into the swing arm. This "cap" limits my ability to get any tooling behind the race to extract it. This "cap" doesn't show up on a parts list as being available/replaceable... How has others dealt with this?
