I'm not saying just because it's got a chain it never needs looking at just not for a while and it's more mileage related when the likes of a belt has to get done at age.
As for the brake fluid I would still change it every couple of years the reason being is that it's hydroscopic i.e. it absorbs water.
As for doing your own servicing it's up to you.
I used to be a motor mechanic and now fix trains but I still use someone to service my car. The reason being is the guy i use is a mate he's very cheap £25 an hour and he works on cars every day when I don't plus i trust him 100% to only do what needs done.
