questions on fixing up polaris

Hey guys i have a friend w a polaris 400 i think its a sport? but either way we are wanting to fix it up and have been having a hard time finding any info on parts for these things! Is there any type of better suspension we can get for them if so what and where?? can the outlaw or predator shocks be fabed up 2 fit? I would like to lighten the bike up a bit as well, so do they make a diff sized or aluminum wheels for these bikes? How bout the swing arm?? Any help would be greatly appriciated as i ride a trx 250r and dont really kno anything about this type of bike!!! I would really like to fix this one up because it was my friends very first quad and it has alot of sentimental value to him! Thanks in advance!!
