You guys are worrying too much...
Ticking is going to sound different depending on,... how close you hold your head, your hearing, how loud yer' muffler is, what helmet you wear, whether you have a windshield, if the chrome covers are still on, temp,... and finally, how much you worry about it...
Don't worry... use decent oil, adjust vales to speck... if there is any damage, you can't undo it,.. so just enjoy riding and fuggetaboutit...
A big, air-cooled thumper is going to make some noise,.. ticking,.. and it will change depending on a hundred different things...
That said,.. if it sounds like two insane chipmunks beating each other up with hammers,.. you probably have a problem...
