Wasn't on the TRX , but my previous bike (FZ600) had a "ticking" at low revs which I, my neighbour, and the mechanic at the shop all thought was a loose tappet.
After a lot of checking it was traced to a minute air leak at the exhaust flange.
Rubber side down, Red side up is my preferred riding style.

A bit of ticking is normal, in fact desirable (assuming it's coming from the head/valve-cover area).
Correctly adjusted valve clearances will make a ticking noise when the engine is running as there will be a small gap between the cam and the cam follower (bucket). This gap ensures that the valve seats fully and seals the combustion chamber. The tick is the sound of this slack being taken up as the camshaft rotates.

If the engine is quiet there's a possibility that the valves aren't closing fully due to being held open by the cam which will reduce power and cause damage to the valve and valve seat due to blow-by gasses.

"A ticky engine is a happy engine".

If the tick becomes a clatter then you may have a problem.
