The mechanic at the dealership I spoke to said - we get people riding in with rattling cam chains now and again.
He also said - it's not that uncommon, usually newer lower mileage bikes, but he's never come across bent valves due to a failed tensioner.
So presumably, whilst starting the engine with a dodgy tensioner perhaps isn't a great idea, it doesn't often result in damage.
I'd have thought (guessing) the biggest risk is from those who hear the rattle, and think, I'll have a look at that at the weekend, but continue to ride the bike and give it a bit of a thrashing.
Got a young lad at work with an old BMW car, the cam chain is rattling. I told him best fix it or get it fixed before the chain jumps and you end up with bent valves and a much much bigger bill to fix. He's been driving it for months like that now! Wouldn't be me.
