What dealership was that? The dealership's I've called in GA were $80-$90/shop hour.
You can plan on around $500 +/- for the 10,000 service. More if you need your valves adjusted. Mine didn't have to be adjusted.
As far as other dealerships in GA... Atlanta Triumph - closed, Moto400 - closed, Triumph of N. GA (A **** good dealership) - closed.
I haven't heard anything good about Triumph of Augusta.
Freewheelin, is okay... not good, but okay. I think their shoddy work caused me to get stranded in Arkansas... no proof, but...
Since I'm no longer under warranty, I'll be doing most everything myself...
My brother in-law is a Harley tech, so I'll be getting some help from him and around here...
But, IF you find a good dealership in Ga, let me know.
