2002 500HO Carb Jetting sizes

Hello, new to the forum. Just picked up this ATV and looking to have it run a little stronger. I’ve been reading several threads here on this issue but I haven’t found exactly what I’m looking for?
I’m installing a K&N air filter and want to bump up the jets to maximize performance. I noticed that without an air filter and cover, it bogs under full throttle. Can someone recommend the max jet sizes to accommodate the (hopeful) increase in air with the K&N? I wasn’t planning on changing the exhaust (I’ve been reading that some here say performance is negligible?), however, if someone has a noticeable performance increase package; air, jets, exhaust, – I’d love to get that info.
Thanks in advance!
