Get the work done in the Spring.
You should be good for another 40k - 80k with minimal maintenance. Any problems and the work will be guaranteed,
Guy has a good reputation and stands behind his work 100%, several threads on here will vouch for that.
These bikes are relatively easy to maintain. Some great guys here on ADV to help if you get stuck.
Get it fixed and enjoy it for a while.
