Hey, I have a 2001 Polaris XC SP 600 and they guy I bought it from had a Hot Seat Perf. Boost Bottle put on it. I was wondering if this actually helps with fuel economy, improves performance, and all that other good stuff the websites say it helps with? Are they that helpfull in these areas? What would be the best place to get new Carbureator boots for this sled? I have cracks right at the base of where the bottle connects into the boots, small ones, you have to push the bottle back to see them. I figured not a good thing to have, regardless of how small they are. I am looking for a good place to get new ones. Thanks to any advice.
