Noticeable vibration at 200+ hours 912iS Sport

Would it be 20 grams?

Unfortunately I was not able to conduct my usual vibration test due to clouds and weather on the way back. I'll try it again this weekend.

Hi Jim,
I kind of depends on how bad the vibration was and if you have ruled out all the factors on the plane that can cause vibration.
Common causes;
Tire out of balance
elevator loose
prop blades not at the same pitch
prop out of track
loose wheel pants
prop needs dynamic balance
gearbox needs reshimming
