sorry for the late answer. Im getting one of theese. First of all, about the noise, I dont know the words in english, but i think its something in your exhaust system running a bit loose. A guy in another post has already sorted that out. The oil, its normal it leaks. You just put 2 stroke engine autolub if I got it right. It will not work verry well, as its not the right spot to put it, and not the right bike. You have a 4 stroke bike chap, not a 2 stroke. 4 stroke only require oil in the brakes, suspension, and carter. And whatch out! Those are all diferent types of oil. Better to get at least an advise and some highlights from some person that know about mechanics or even your regular mechanic, if you have one.
