doesn't rooski make these bolts or is just the cap bolts??

cheers ill try the coke can thing

Where is it "sliding from side to side" in the actual forks or where the stem base joins the quill (shaft)?  If the latter then the main bolt is not tight enough or the quill is not seated in the stem base properly. 

A coke can won't help in that instance as you will need to either get it pressed in or tightened up sufficiently.

I found similar with a chrome set of handlebars, there's lack of grip to a shiny chrome surface so I smeared a tiny bit of valve grinding paste in the 2 half moons of the stem and gently clamped the stem in the correct position and moved the handlebars back and forth, tightened it a little more then done the same again.
I then removed the bars ,cleaned the stem / bars thoroughly  , it made the bars hazy in that area but now they grip.

Yep, that should do it.  What I did was mount the stem in the forks, put some electrical tape round the large nut and on the stem (to avoid damaging the ano) and used a long adjustable spanner to nip it up tightly.
