why do people link to BlackMagic Racing for polaris stuff? haven't you done that before ZRT? Black Magic is 100% arctic cat(though I hear they are working on the RX-1). Am I missing how you access the catalog on the other site? Its canadian so it won't be a great help anyway but I don't see how to access the catalog unless I enter the page number.
io put K&n on my 96 mxz 583 and i final got the jetting right after installing a pyro 2000 egt setup and my stock jetting was 240-250 and pilots 50, after k&n the pilots are 55 and the main jets are 350-360, i had to jet up 110 sizes, and these setting are correct plugs and the temp agrees, you may have opened a big can of worms with them also if you do any powder riding or when its snow hard to will need prefilters, my carbs would get a nice coating of ice on the inside becasue the filters get a little warm due to under hood temps and then the water vapor goes through and since the gas in and the carbs are cold it coat the inside with ice then it runs like crap. nmot trying to scare you but thats what happened to me. those filter ended up costing me about $200-250 for other parts to get them to work right
