Re: engine rattle
It won't be the oil. A 0w-40 is thinner than a 10w-40 when cold but the same when hot (which is ideally what you want). I have used this grade (And 5w-40)in several twinnies with no problems.
They have C0cked up something at the belt change almost certainly IMO, especially as since the change the noise has appeared.
Probably the timing is out, or a tensioner is not fitted correctly.
