Thunderbill Welcome to the family. Check the tyres and pressures. Just go around the bike a torque the bits up and come back let us all know how it is. How does the motor run. Joe.
You tried jacking it up and seeing if it still occurs so u can see whilst not on the bike. Also if wheels are off the ground would remove them from the equation. Obvious caution re any vibrations not shaking the bike off what ever method is used to jack it up
