Dealer policies vary. The shop I work with would be the same. But what about a trip to a distance destination? I don't know.
As a matter of fact......it happened to me. Coming back from Sturgis I had just left Yellowstone and was in Idaho (a long way from California) when the cam chain tensioner shoes failed. I guessed what it was, right away.
Having HOG Road Service, I called for a flat bed and they hauled it to the nearest dealership......about 35 miles away. Sure enough, I was right. And they could have it fixed by Tue (this was Sat evening). I quickly calculated lodging costs, lost work, etc. etc. and then, what if there were some issues with the work done.....I'd have to bring it back to them to get it corrected.
I rented a car and had them ship my bike via the HD shipper. And now my bike was with somebody that I knew and trusted. Shortly there after, I went with the Freedom cams and haven't looked back since. My dealership still stands behind the extended warranty.......of course, I've never had motor issues, since, either.
