My TE ie vibrates at 6900-7000rpm, is this normal for these machines? Horn and light mask resonates quite a lot, especially horn. Lower than 6900 no vibration, over 7000 vibration also goes away.
These are smooth counterbalanced motors. For such a narrow range it might be a local resonance. Move stuff around a little, tighten a few bolts and see what happens. Maybe add handlebar end weights.
This was happening both stationary and in motion. There was something loose inside the horn and it was making a loud buzzing noise. I was almost sure it came from the engine
