Carb jetting 2002 polaris 600 edgex

[simonsr1]

Just curious if anyone has changed the jets in their sled, what sizes did they go with

[simonsr1]

anybody change any jets/needles beside the main jet on this sled

I ride in Michigan and Ontario only and find the factory jetting to be perfect for those elevations. Performance wise all my edge poo`s have run great so again no need to change them.

I just went up one size on my sled this year.(may have been able to go up 2 sizes)
I have been running this sled for 5yrs and never had to change the jets. I noticed plugs were a little lean.( I'm thinking the 10% ethanol in the gas now made a differance)

Interesting comments on the 600 motors in MI. Both my 2000 and 2005 600's came stock with 440's which work great at sealevel. The 2000 had been changed to 410's when I bought it. The jetting chart for the 2005 also says to use 410's for MI altitude so those have been switched too.

The 2005 with the 440's ran very fat, plugs almost black and very doggy. Runs much better with the 410's and plugs are a nice tan.

I have read other threads on here with guys running 400 mains in MI with stock motor and airbox, but that would seem to be on the edge of too lean.....

Are you really saying you run 440 mains in a Pol 600 motor in MI with great results? Just seems hard to believe based on my experiences -

I can only comment on the sleds I have owned which were a 2001 xc700, a 2002 xc600, and a 2004 600 classic and I left them all with the original jetting from the factory. All my riding is done at an altitude for the most part between 600 and 1000 feet above sea level and they have all been great running sleds for me and ran strong with no problems and no meltdowns. They may have been a bit on the fat side but I prefer them that way anyway. I dont want to be out on a cold 5 degree day and do a wot pull across the lake and burn a hole in a piston. I always preferred a richer set up with a two stroke as they count heavily on that extra gas and oil for lubrication of the lower end as well as up top. They probably would have been a little snappier if they were leaned up a bit but I was happy with the way they ran stock for sure.

thanks for the responses, my idle was way to rich, loading up when idling, so I just ended up leaning idle out a little with fuel screw, made a huge differance, throttle response is a lot better, also went one size leaner on the main jet,

i had the same sled. i never touched the main jets , but i did drop the needles 1 notch. the sled really woke up after that. ran it like that for 11000 miles. plugs were always perfect. engine was stock with air tubes removed and a clutch kit. best sled i ever owned.

snowchick - what do you mean air tubes removed? did you gut the air box?? I thought when you gutted the box, you have to richen the mixture up.

I have a 2003 xc 600. I dropped the needles one and It runs good. Just have to keep the exhaust vales clean its pretty easy to do every 800 miles or so.I played the game with running them lean.all done with that I would rather ride then put engines together.

The only real problem I was having was at idle, feels like I have that fixed now, I check and clean the exhaust valves every 1,000 miles, I use amsoil intercepter, the valves have very little build up, and very easy to clean, not like when I used to use polaris oil

thanks for help guys

sorry for the delayed response. i took out the tubes only in the air box. i left the plastic plate in place. i had brown paper bag plugs and never fouled out a set of plugs. i usually rode about 1500 miles a season and used the same set the whole season. i used interceptor as well. cleaned exhaust valves every 1000 miles. last season i switched to the amsoil hp with out any problems.
