Windshield wobbles while braking
I hope someone of you may give me an idea what is the problem with my bike. It is the 2004 Honda CBR 600 RR and the issue is the following: let’s say I am riding with 150 km/h and then I brake, when the speed decrease to 95 km/h the windshield starts to wobble, then at 75 it stops and starts again when speed is 40, and it stops again in 25 and is missing till 0. The trebling is very fast and it is only on the windshield, the range of moving is about 2-3 centimeters, up and down. The levers and the handlebars are not shaking at all, I don’t see it and I don’t feel it on my hands and fingers. The problem started in 2017 and I am not sure why it started. My tires are new, front is 0617 with 4*000 km on it, pads are new, I’ve changed the bearings on the steering wheel (no slacks on it), the bearings on the front wheel, I’ve serviced the forks, the suspension settings are standard, I’ve been riding with 3 different pairs of front discs (not new ones) and it does the same wobbling with each of them. The braking calipers are serviced and there is no leakage, nor signs of damage. Both rims have small curves (1 on the front and 1 on the rear) but when riding even 180+ km/h there is no problem, no shaking.
Any idea what may cause this wobble ?
