yeah its at riverside. The sounds do sound like a chain banging around inside... could the engine be totalled if the pistons have banged into the valves?

Not necessarily. The head will definitely need to be re-worked if the valves got bent from the piston slamming into it. Depending on the force, the pistons itself may need replacing if there's a love stamp left behind from an opening valve, but you'd have to pull the head to find that out.

Also, was there a particular RPM that the tapping noise became more apparent? Say while riding at 6-8k RPM, or was it constantly there at around the same volume at all RPMs?

So you did an oil change and then the engine went... Did you just put in 3.3 and then call it good or did you actually check the levels?

Could be many things, I am betting CC with the sounds you are describing, but hard to say, the shop will be able to find out and hopefully you will get everything replaced under warranty if you still have it.

Then it just sounds like you were one of the unlucky of a mass produced product. Hopefully your shop has some quality techs and they get this shit fixed soon.

The OEM tensioners use a spring tensioner. Many have replaced the OEM ones for the APE manual tensioners.

This was a huge problem for gen 1 bikes (06-08), I don't have a 2nd generation bike, but I don't believe the 2nd generation bikes fixed this issue, so it's probably safe to assume that they all suffer from this.

However, if you use the Triumph kit tensioner, it'll solve that problem since it uses a stiffer spring, but it costs 2x as much as a manual tensioner.
