I just bought my 1st atv a 2000 polaris trail boss 325. Could I get some performance tips for this quad?

I would also like to know what is the best air pressure to have in the tires. They say 7 psi max. I want to keep the upgrades as simple as I can. Thanks for any and All info. P.S I have heard that these are a nice reliable machine, what do you think?
