Maybe I should look into using the Neo motors with the GTB if the Novak offering is problematic.
Id put my money on an out of balance shaft. It will sounds smooth at certain revs, then vibrate like crazy at its resonance frequency. If i were you, email novak about this, they might be able to rebalance the shaft, or just buy another one.
I personally love my GTB. amazing power. Im having trouble driving smoothly, its too tempting to slam down the throttle out of turns!
