I would start with the basics first. I bought a new to me 95 polaris sport last year. it had not run in two years. I tried to start it when I got home and it did the same bogging you described. Solution: new gas and plugs= a reliable sled. But to answer your question on my 96 XLT $480 for carb cleaning, sync, new jets, new carb boots, new exhaust gaskets(affect back pressure) and alot of crying but the sled screams now.
