Can Anyone Diagnose This Tappety Sound? Or Associated Costs?

looks like the exact same bike as mine, I’m like you not an expert on this but keen to see what others say on here.
How many kilometres has it covered?

 

It's always hard to tell from a video but I'd say that is tappet noise. It wouldn't bother me personally but if it did, the first thing I'd check/get checked is tappet clearances. I've had some camchain/tensioner noise in the past (900 engine) but it was more pronounced than that. As for the cost of any repair if needed, if it's under warranty, no cost. If out of warranty it will depend on the price on any parts required plus time spent working on it so get 2 or 3 quotes if possible.

 

Yeah sounds like a tappet to me too.

 

Don't know about your bike but the tappets get tighter and quieter on the triples I believe.
