V4R here. +1 pivot, 90nm rear spring, forks about 3mm from the clamp. I'm feeling head shake when reaching 150mph on straits on track. Rolling off gas, immediately removes it. I have a feeling when I re-apply gas, the bike is more stable. Any ideas what can cause it ?
Dave Croft came back with few suggestions, will try them tomorrow. But I did think the same as you said.
So turns out whoever prepared the bike forgot to install 90 spring and I had original 105. That can explain the front shake easily.
