ummm, its right in the manual to do it at 1000km(620miles)
And EVERYONE I have seen that talks about it had all their valves tight, even very tight, especially the exhaust. That's bad, because if it gets too tight you will burn a valve.
mine is an '18 bought in Oct of 18. If yours is newer, than that, maybe they have changed it, but its clearly talked about in my manual, and its part of the service when the dealer prints out whats done at that service
it was just under $600 Canadian
