Ht 66, 150 miles on it..... Take off to mid cruising speed motor runs fine,,, Above this the cylinder and head shake violently... If i go from cruising and give it full throttle it will not shake as bad thru this rpm range....
Above 2/3 throttle is smooths out a little, but still fairly bad vibrating...
Could upper needle bearing be bad?? Any ideas???
Thanks as always....
