i have a 04 mxz rev 600sdi and have been having a problem with it the past few times i've ridden it. its only has about 50 miles on it now but, when i first start it up it doesn't want to stay at idle. its slowly just shuts off. i can keep it going if i rev it a little. if i try and ride it, its like somethings holding the sled back , it wont go above 40 even at full throttle. then all of the sudden it will run and act fine like someone flipped a switch. its only acted like this twice but what do u think i should do?

up the idle to 16-1800.

why would it run like sh3t if the idle was just set to low

make sure the tether is snapped on good. It shouldn't go over 3000rpm if it isn't connected but if its losing contact here and there it could cause you problems. The lights on the sled would light up too though. If it only has 50 miles on it, take it to the dealer.

thanks for the reply. im very new to sleds, this being my first one. so i dont know much at all yet. could someone tell what the tether is??

That's the cord attached to the ignition cap that needs to be on there good but that can't be your problem because it limits your rpms to 3000 and your clutch wouldn't even engage. Your problem is because you haven't burned out the computer chip in the MPEM that retards your timing for the first 300 miles and has a richer fuel map (= wet fouled plugs and poor idle). So keep a pocketful of fresh plugs in your pocket until 300 miles and just deal with it.

Perhaps the dealer threw extra oil in the gas for break-in and it's loading it up? I know there not suppose to, just a thought. Don't think I'd be playing with the idle at only 50 miles.

Just another thought, and not trying to be smart here, but if you are new to sledding then it would be wise to spend some time in your owners manual so you understand the basics of your sled. The dealer should have walked you through the basics, and you should definitely have been told about the DESS and the tether.

thanks gman and guys. i was never one for reading the owners manual other than finding out how to maintain it. i think ill do that though

I've read my owners manual like 3 times just to know where everything is on my new sled. When I got it, I read the manual before I went for a ride. I made the Mrs. read hers before she rode. I got the basic info. out of it and found so much more here at SW. The best advise in the manual is suspension set-up, belt p/n, spark plug pre-gapped over priced frikin plugs(sorry). Oh, and I had to look at it again to find where I put my spare plugs. :)

You're very welcome. Unfortunately the manual doesn't tell anything about the 300 mile break-in chip (at least they didn't on the '03's) so my dealer got an "earful" from me when I first got my sled. He just says "Are you done yet?" and then explained it all to me! :lol:

Enjoy your nice ride!

Good for you. A dealer should walk you through the delivery of the sled. When we bought my Legend they wouldn't let me leave till there shop foreman went over the basics of the sled and made sure I understood. Very impressive.
When we bought my wifes Classic they couldn't get it on my trailer fast enough to watch my taillights down the road. Guess where we'll look for our next sled???
