Welcome along Dan.

Just keep the revs up (ie don't labour the engine too much) and enjoy the miles and smiles!
IMHO, the most effective mod for the money is to lower the final gearing - eg +2 teeth on back sprocket or -1 on front. You loose a bit of top speed but gain improved acceleration. Can give the engine an easier life as well.

However, as it's your first bike it's best to just get used to it first.

Enjoy!
