97 XP 780 Carb information

[Kelsey M]

Hello

I have a 97 XP 780..

I have no manual so I am curious as to what carbs I have (BN's, other?)
aslo what jet style do these carbs take? Standard Mikuni Hex head (big Head) or the smaller round Mikuni Jets?

Last, what would be a good jet for 5000ft running with a totally stock engine?

Thank in advance
