This is my second engine in the same bike. So, it's a 75 engine in a 78 bike. I would not expect the engines to sound different... but on the new engine i am getting, what i think, is cam chain noise. I would describe it as a rubbing sound that you hear get more frequent as rpms go up until about 3000rpm then it seems to disapear (or get to tight to hear)... at idle you hear it about ever 1/4 - 1/2 second.
I have adjusted the chain multiple times now, along with the valves (.003 & .005 [spec is 002 and 004]) and they are both good. The sound doesn't seem to change. It made the sound since the first time i started it, and i changed the oil after 1000km: there was ZERO debris in the sump, and there was some metal in the small filter...
However, i should ask, if I adjust the tensioner, and don't adjust the valves, will i have a problem? - i just ask because i have tappet noise when the bike is cold, but it gets quieter as it warms up, which is why i think the valves are okay...
the bike seems to run great, starts strong, idles strong (after it warms up). I am usually at about 3.5-4rpms in 4th doing 50-60mph, and in 3.5rpm in 5th to do 60mph.
I'll get a recording when it stops raining.
