Had some hands-on experience the other day.
My engine: approx 45,000 KM. Said to have a top end "Overhaul " at 30,000KM. Hmm?
The tensioner extends for 18 mm.
The chain is shorter than the Suzuki limit ( 21 pins 126.75 mm).
The chainwheels do NOT look worn.
The tensioner guide has a 1 mm deep channel. Don't know if this is normal , have not measured a new guide.
Q:
What is worn?? I.a.w. what needs replacing.
