So it would stand to reason that it would make more noise if it didn't need to be adjusted.
This bike in question may have a problem. I don't know.
My bike has always sounded like a sewing machine and I have never had any problems. It sounds like all the other WR's I have seen or rode with.
I have always kept the valves in spec.

well yeh, this also sounds like a old sewing machine. so this is normal? also what do u mean how the valves get tighter over time not looser? so this then in theory wouldn't make it noisier?
thanks again guys

Usually when the valves are out of spec the bike likes to start with the hotstart engaged. When valves are out of spec the bike becomes a bear to start, when adjusted correctly the bike should start on the first kick.. Trust me WRs are NOT known to have a clicking sound or Tapping noise when properly setup..

As the valve wears it rest higher in the seat and the gap between the lobes of the cam and buckets grow smaller. Under the buckets are shims that can be replaced to get the required gap.
Every WR I have seen has always been a little nosier compared to earlier 4 strokes.
