Dear LARGE Person,
I live in Norway. The Nordkapp is like Ushuaia in Argentina. It´s "the end of the road", it´s worth saying you´ve been there. However, it is far from being the best of Norway. The country has a lot more to offer than that, particularly the West Coast and the Lofoten Islands. As Grant says, come in summer, and even then get ready for A LOT OF RAIN, which, combined with the latitude will mean it will be a bit chilly. That is, unless you are lucky and get an exceptional summer. But, since the weather is always "on the move" you will still have a great trip. Fuel is about 1.20 USD a litre (!) and just about everything else is VERY expensive but the good thing is you can camp anywhere for free. So, you can also do it on a budget.
You can get two stroke oil no problem in just about every gas station.
If you come this way, you can contact me if you need a hand. I live in Oslo.
