Last year I bought a 90's polaris trailblazer 250 that the guy said all it needed was a battery for $250. It turns out that the motor is missing alot of parts, so im going to take the motor out and give that to my grandpa since he has a trailboss. My choices for motors that are available are a older arctic cat 440 fan, older ski doo 550 mx fan, or a 88 indy trail 488 I think. Oh its not the indy I ride it is a different one. I have looked up many things on this and im pretty sure I will go through with this project.
