Has anyone installed or had direct experience with the RCR Stage 1 Performance Upgrade for the Polaris Trail Boss 03/04/05? We have the 03 Boss and I'd like to get some more power out of it. Would much rather upgrade the Boss with an RCR kit that makes it perform better than go buy a whole new ATV.
Thanks.

 

I had the local shop install mine - woke it up big time. Vented air box with after market filter, 145 main jet, primary spring, E slip on.
