Hi Lewis,
I am guessing it is you that has been posting all the messages about getting it to go faster top end wise. You bike is very low miles for year and in time should loosen up a bit more.
There are a few things you can do but dont go messing around with carbs etc unless you know what your doing otherwise you bike wont be going anywhere.
If your old enough buy a 125! But if your not
You can change Pipe and airfilter. This will make thing a little faster but not by a great deal. You will have to rejet your carb but the people you buy the bits from will tell you which size. You may be able to change size of the sprokets. this will give you more top end but less accelaration.
You can also get tuning kits/big bore kits. Check the back of motorcycle news for dealers.
Personally, but I am old and not 16, I would keep it original and it will be worth more and buy a 125 when you 17. But then again I know how important these things are when your 16!! In which case sell it and buy a Runner 50.
