Well it's been one long continuous event to find the problem but the result is now in.
Mike gave his Tiger to the Auckland Triumph dealer whom he bought the bike from (incidentally this is the 4th Triumph and 2nd Tiger he has bought from this dealer).
The dealer appears to have just stored the bike waiting for Triumph to 'approve' the warranty repair without diagnosing what was wrong with it, he has only had it less than a year.
Not happy with the delay he withdrew it from that dealer and took it to the second Auckland dealer. AMPS, these guys were really helpful and three of them all tried the bike, one of them also owns a Tiger, and all agreed there was something wrong with it.
They gave it a new power tune-up which improved the handling of the bike in slow traffic but still the vibration persisted.
It was eventually tracked down to the front tyre which appears to have delaminated within the tyre letting air inside the body of the tyre itself. The tyre which was stock, Michellin Anakee was replaced along with the rear (with Metzeler Tourances). Problem disappeared. AMPS said this was the second case they were aware of that the Anakee had delaminated.
