Glad to hear your dealer saw sense and decided to exhibit good will, they probably realised it's more money to them in the long run. It's always a pain trying to get over a faulty bike, i've sold a few bikes for faults that I couldn't let go of even after they were fixed-particular issue of mine is a dropped bike, never the same.

If it doesn't happen again, i bet they had a trainee mechanic do it first couple of times and he bodged it
