yeah i figured it's pretty common. but i'm sure something can be done just because mine didn't do before.
maybe the way i installed the engine this time on the mount. too tight or too loose. i did installed the bolts and nuts opposite to previous time.
and i noticed that one of the shims touch the engine case. who knows ...maybe that transfer the engine vibration better now. maybe my engine vibrates more now because of different
valve clearances . maybe the covering got loose somewhere in the wing . i'm sure there is a reason for that. i refuse to accept this it was so much nicer before ...
