The stock slide is a #6, you want a #5. It is pricey, though, about $90. You can make yours into a #5 by grinding 1mm from the airbox side of the slide, but it is permanent once done, so be careful. You won't regret this mod, it transforms the running manners and power of the engine completely.
There have been several threads on the proper way to cut a slide, just do a search. I believe there was also an article in MXA on this as well, either this month or last month.
Also, Those are the jets I run in 90+ degree weather here in Georgia. I jet slightly richer in the winter. I don't know the temps or altitude where you live, you may want to start one size richer than those sizes and see how they work for you. The slide mod is a must for that bike, though. You will never get the most out of that engine without it.
