Ordinarily the cam chain "should" be ok at that mileage. But worth inspecting it when you lift the rocker cover for condition, it should be tight still on the sprocket (not be able to significantly lift links away in the centre) and with the adjuster able to exert gentle pressure to prevent slack. Realistically it should be more than capable of twice that distance without a problem. If it meets inspection I'd be confident it's not going to be a problem.
Consideration if you want to change it is that it's endless, so crankcase split and crankshaft out to swap. I know there's some you can join in situ but although I'm quite happy to join and hand rivet most chains, I chicken out for cam chains unless there's no option.
In addition to that, it's the primary chain that's ordinarily more vulnerable to premature wear, so if you split the cases you'd plan that as well.
Worthwhile pulling the sump to assess the primary as it'll more or less dictate if more in depth work is sensible.
Really then, inspect the chains and consider from there.
