Hazza, I own three different Triumphs (two 600cc and one 955cc) and they all make injector noise. As for it being as loud as tapping hard on a mouse key (laughing as I try this) I would say that is a reasonable noise frequency so long as your finger is not smashing down on it. The sound will quicken with the increase in engine RPM's, as the injectors increase their opening/closing speed, and will eventually become another instrument in the beautiful symphony that the Triumph engine produces. You might call around for a mechanic/dealership that will be kind enough to at least listen to your bike before you have to pay them for anything. It would be very shady for a business to charge you to listen to a bike for 10 seconds just because you don't have the experience with it to tell what a normal or odd sound is.
One trick you can do to see if the noise is due to exhaust getting past the valves (caused by the above described worn valve seats which is very unlikely with your bike’s miles) is to take a piece of letter paper and hold it up to the exhaust pipe outlet as the engine is running. Hold it tight up against the pipe to block of the air flow and then let go of the paper. If it sticks to the pipe and bends in and out, you have warn exhaust valve seats. (This is caused by excess air sucking back in as the piston moves down in the cylinder.) Another thing to do is to listen to the sound as you continue to ride, and if it begins to get louder with the more miles you log you might consider having the valves clearance checked. As I said before, it would probably be a good idea to do so if you have no paperwork saying it has been. On that note, a Triumph dealership might have your bike’s VIN in their computer, assuming all maintenance was done at a dealership, and they could tell you what has been done. Long reply, but I hope it helps.
