I got an all-stock '93 polaris trailblazer for eight hundred bucks and still have over one thousand left, what engine upgrades would I need to make it a nice dune quad

 

Hello SKC. Go over to the Polaris forum and post this, you will get some good response. However, a clutch and pipe kit from Rick Ritter will do wonders for the engine. Next, a set of Douglas blue rims with GBCs tires front and back similar to the ones I run. All this should be well under $1000.
