I have a 2017 wing with a Roadsmith kit. I believe it says in the manual that it should have the valves adjusted at 30,000 miles. It currently has 27,000. This may be a stupid question but what is the purpose of having the valves adjusted and what happens if you don’t have it done? I traded in my 97 wing with 53,000 miles, never had it done and It never was an issue. Also, what would be a reasonable price to have it done?
