I would think 5w30 is too thin for an old KR engine, surely 10w40 would be better.

Spot on

10/40 semi would be the better choice, 5/30 is way too thin

Cool so really 10W40 is what should be in there, I grab some when - get paid and change it out

Yep 10/40 will be fine

Would having oil that too thin cause any major probs? Just paranoid now :p its at the corrrect level etc

No it will be fine in the short term.

No it won't cause a problem, except the engine may drink oil as tolerances between parts on old engines aren't as good.
