dont run it with the stock jet! you will probably roast a piston.with a aftermarket filter and air box cover you would need a 280 or so.
You need more than a #260 main, if you are prefixing at 32:1 then the smallest you can go is a #310 and plug chop to confirm.
The stock needle should be moved to the bottom clip for a start, you may find it can come up one.
If you run with the stock jet, be prepared to a rebuild soon, the piston will cook.

Recommend authentic Mikuni jets. Makes it easier to help tune your bike as all the advise on BF assumes you are using Mikuni Jets. Other jets are not necessarily the same size.
For example:
Blaaster is saying use a #300 Mikuni Jet.

well i run the pro x jets with absolutely no issues.and from browsing around the forum the sizes seem to be the same between pro x jets and mikuni jets.
at sea level i would probably use a 300. if you are planning port work I would order 300 - 340 to be safe.
What is your altitude?
What is your altitude?
Start with a 300 with current mods and plug chop to confirm. It may be pretty rich so order a 290 as well. at your altitude you might find a 290 is better. but start with the 300.
