If there are any engine gurus out there please may I ask this question: What effect would it have if the balance shaft had been put in one or two teeth out? Trying to think of a reason for the excessive vibes that start from around 5k-5.5k then get worse right up until red line. Mechanic acknowledged it was bad and the demo bike I tried was at least 50% less. I can live with it but would rather not if there is a solution.
Thanks in advance.
