stock should be 420 with 45 pilots.Originally posted by Toyman
[br]Thanks for all the great info. I took it to the dealer do to sheer boredom and lack of snow and this was the out come. I had NGK plugs installed (BPR9ES), he put the recommended Champions back in (Polaris and Champion designed the liberty ignition box around the recommended Champion Plug?). Found plug boot not connected to the plug wire, cut plug wire back and screwed boot on. "Fiddled" with the carb air/fuel screws. There was a little snow at the dealers, took it for a ride, ran fine. I will be running 400's as soon as the warranty is over, I believe it has 450's in it now. I will not know if it's really fixed untill we get some snow. Thanks again for all the help.
