Ive been playing around with the tightness of the steering head bearings and you would be surprised how much they can affect the feeling of the bike. They are a cheap steering dampener if you ask me. I want to try some really thick grease in the bearings to stiffen them up some. Its tightened up as far as Im prepared to go without risk of damage but Im looking for some more stiffness to control the odd headshake I get. Does anyone know a way to thicken up regular grease or a grease thats very thick?
