I've only come across it once and it was on an FJ1200 that I fixed for a friend (same symptoms). Shift rod is a very similar design to the FJR. I just swapped his shift rod compete with damaged spring for one of my spares. To change the rod on an FJR involves a fair bit of burrowing so I think $300 for a dealer to do the job is pretty good. Personally I think the dealer should be doing it for free. In the UK the dealer would be liable even on a second hand machine if the failure happened so soon after purchase (they can't cry sold as seen).
