Won't do it any damage it just restricts the power.............
You worry too much!  Although I have heard that if you twist the throttle too quickly it can come off in your hand and the brakes fail as a result of this.....................

I don't particulary want to take the restricter out just yet. |
You can't really run a bike too fast persay, it will go as fast as the restriction will allow it, ie about 100mph. The restrictor is generally a circular piece of metal with a hole cut in it, placed between the carburettor and the engine. The hole is a specific size to only allow up to a specific air/ fuel flow to the engine so that the engine can never develop as much power as it might be able to. This is an effect very similar to just not using the full range of the throttle.
There are problems with running any engine at high speeds for a long time, no matter what its state of tune of course. Run an engine at the redline long enough and it will drop/ bend a valve, start knocking, overheat, sieze, break piston rings etc etc.
One thing the normal restrictor won't do is cut the power at a specific point. It is restricting air/fuel flow right across the rev range.
There are bikes from specific markets which do cut the power using the CDI and/ or fuel injection, either by retarding the ignition or by cutting the fuel injection. Japan and Germany are two such countries I believe.
