Yea, go up two teeth in the back and down one in the front.
520 if you want, but I think the stock chain size should suffice.
Check the price, because you may want to change out the chain anyway if you get new sprockets, not changing the chain is like changing your oil and not changing the filter (or so Ive heard)
You should be able to bounce her up without trouble though.
Second gear, 55-60 mph, stand up, let off the throttle quick, bend your knees, give it a big bounce and whack the throttle quick and HARD! Keep your arms and legs straight, your bike will bring your big self right up.
PS If you try this, careful not to flip over, if you do it right, the bike will come up FAST
