I need some jetting specs for a 2003 800 RMK for 0-2000 feet. What are the air and fuel screw turns, main jet size, needle clip position. This sled has a holtzman attac and slp air box kit. with 450 mains right now.

How can I tell if this sled has the updated valves. Is there a number stamped on the valves to identify this.

Thanks

I have had an 2005 edge 800RMK and had 470 main jets in it for 0-2000ft, I installed an slp air horn and had to move up to 490's. Needle clip and everything else was left the same, had to fire it up and adjust the idle was all. The only way to know if you need to change the needle is to see if it's running to rich, check your plugs to see if they are burning clean or not. As for the valves, just pull them when you have the carbs off and inspect them if they look good I'd say leave them in, if they look scorced or frayed then I'd replace them.
