I had my forks out to install cartridges, so I decided to tighten a bit steering head - it seemed a bit loose before. I took off cover and nut, but problem is the star nut will not budge / move any direction. Is it supposed to be moved by hand or some tool is needed?

 

They recommend a tool to get in between the triple tree. If the top tree is off and it won't move take a cloth and wrap it around the star but to grip it with vise grips. Or I use a flat blade screw driver and a mallet

 

Screwdriver and mallet like above. I do mine by feel. Re-check after torque applied to the steering nut it changes the adjustment.

 

Yup, same here w/ the screwdriver and mallet. Getting it right is a pain in the *** like stated above, just when you think you have it then it's off once you torque it down.

 

Thanks guys. I'll try screwdriver & mallet.
