OK, if I was a little more patient and searched the posts in the forum, I could have found the answers to my questions. Special thanks to "Chubbyrockstar" for suppling his link to the Grand Vista Shop manual.

1. According to the shop manual, the first valve adjustment is not required until 2,000km (approx 1,300 miles) then again at 4,000 km (about 2,600miles) and then every 4,000km (every 2,600miles)
2. The valves are adjusted with screw and locknut. Good news as this method is fairly easy to perform
