Get deep well sockets, if you can afford them - a set with 8mm thru 19mm will cover most stuff.
Also a set of metric wrenches.
Also get an alternator puller-offer, and the oil filter nut wrench, both avaialble at MotionPro for a bit less than $10 each.
The cam chain tool will cost more - to break them I usually just use a Dremel and a small punch, but to rivet the new link, you will need some sort of tool, similar to this (it eill also break them) -
It's a bit salty, but what can you do??
Some guys try to avoid that cost by trying to do the riveted links with vice-grips or even ball peen hammers - I wouldn't recommend either of those techniques, personally.
And on any old motorcycle, you'll also need a variety of hammers of different sizes, and a rubber mallet comes in real handy.
Probably also handy to have a set of metric allen wrenches.
And some circlip (snap-ring) pliers, both inside and outside types.
