Now thats worrying.I can explain the setting of the LS needle at the factory but the timing gear thats another. My 100 was smooth running before I traded it in for the 125.You know, my 82 has the same characteristics as yours,the vibration peaks at 80%.Looks like I'll have to check the timing then to see if they set it right at the factory.I'll check the other engines still in the box if any are out too.

Before i proceed though , did you set the timing different from the recommended setting or was the factory setting different from the recommended setting?

BTW did you see any change in throttle transition,topend rpm and idling rpm after retiming the gear?



Thanks for sharing.
