1. pull ur scooters bars,forks and stem off
2. get a flat head screw driver or a heavy long socket extention (works good), place it inside the headtube and tap the cup out with a hammer ( do the same to both cups)
3. put a little grease around the bit of the fsa cup that goes into ur headtube ( to make it easyer to get out if need be) get a piece of wood place ur cup in place and tap it in ( reapeat with the top cup)
4. tap the old fork race off ur old forks and tap ur new fsa one on.
5. grease the cups and bearings up abit, and put ur froks,stem and bars back on.
and thats how it is done...
