Weave into tank slapper at 45mph ish

Hi

I was riding the other day fairly quickly through some nice country roads. As I entered a village I started to slow down, at about 45mph I took my hands off the bars and looked round, when I looked back the bars were shaking and had I not grabbed them would have entered a full on tank slapper.

I pulled over and checked what I could, everything looked ok and nothing felt loose. I tentatively sent off again and at 45 took my hands from the bars again and the same thing happened. On returning home I checked the tyre pressures which were 30 f and 33 r this is what the manual states for under 90kg. Just to be on the safe side I upped them to 33 f and 36 r and went out again. This was a few days later. The same hands off bars at 45 and no wobble. I can't believe that running the tyres 3 psi more has cured it and am concerned that after my spirited riding prior to the original instance was showing up something like a failing front wheel bearing?

I will obviously investigate this further but wondered if this rang any bells with anyone who could offer advice.

Thanks
