Bro, I have my G1 for nearly 9 years now, I have no weird sound from the timing chain and never had one either...
I had other generations of the zx10r and other bikes, I cant say that the g1 is making more noise then other bikes I own.
if you decide to go with the manual tensioner then don't sweat yourself too much it's not that often that you'll need to adjust it, just make sure you lock it properly and every so often just check that the lock nut is still tight.
And check again the cam chain!!!
