I understand that legally, no you don't, some searching on here should find a thread linking to the govt consumer website that says so.
That sounds like the price for a valve-check service, based on my experience with the DR200 & DR-Z250 over recent years, but maybe the water cooling adds some cost.
I don't mind paying a dealer to do the first service, 'cos I'm happy for an expert to cast their eye over the bike. Might be different if'n I was an expert on the bike in question.
