it is just the jetting , drop the needle down 1 position or jet down one size but don't forget to put it back when it cools off

 

Yes the jetting. Your sled, although it is a blast to ride, is one of the most finicky sleds out there for jetting. Follow your jet chart, and pay attention to the temperature. If you don't want to play with it during the day, always jet for the coldest temperature that the forcast is calling for.
You should be able to make that sled run good no matter what the weather, but like I said, you've got to be willing to fiddle with it if you want to be happy with the performance.

 

I'm kind of ignorant when it comes to carbs. When you say drop a needle or jet one size down, is this a manual adjustment or do I actually have to change something in the carbs?
Where can I find a jet chart for this thing?

If I drop a needle, and I don't "raise it" will I burn down the motor becuase it runs too lean?

I'm just learning this stuff.
Thanks.

 

You have to get in there to make any adjustments.
The adjustments you will commonly make are to the position of the needles, and to the main jets.
The needles are located at the bottom of the slides, and you get at them by unscrewing the top of the carb and lifting out your slide assembly.
There are five positions for the needle. To drop the needle you raise the clip. i.e. you move the little plastic clip to the next notch higher on the jet. This will allow the needle to sit lower, and in turn will restrict the amount of gas that can get by it.
There is a risk of burning down if you're needle is too low.
The main jet is accessed through the bottom of the carb. It's not adjusted, but changed. You have to go to the dealer to get different jets. Get a jet wrench while you're there.
Your jet chart should be found under the hood somewhere. It'll be a sticker with a chart showing elevation and temperature, and will tell you where your needle should be, and what main you should be running.
