converting a flatland 2008 600 RMK

[ZR 900]

What do I need to do? Clutch weight numbers? Needle settings? Any jetting issues?

What's the best can?

Thanks

I plan to take the sled to Yellowstone.

We will need a couple sleds but only have room for one. Any opinions as to the best place to rent one out there?

Thanks

Is it EFI or carbed? If its EFI you just need to change the weights,if its carbed you will have to change the main jet and possibly the needle position. Do you have the factory jetting chart for your sled?

 

[ZR 900]

It is carbed. I don't have the chart. Is it posted under the hood? Do you know the needle position? Jets? Thanks

When using non oxygenated fuel with a RON greater than 93,
decrease the main jet number in the above chart by 10 and raise the
E-clip one position. If the chart recommends clip #1, install washer on
top when using RON 93.

So I am thinking 10-56's and a set of 310 jets should work well enough right? Where should I set the needles?

 

[ZR 900]

Merry Christmas everyone!!

 

[jcrjet]

Looks like needles should be in the #2. Another problem you might run into is gearing. I'm not sure about the flatlander shifts but my 08 600 rmk has 19/41 and is still just a bit tall for my preference. You'd be better off with 18/41 or 19/42.

290 mains should be ok and Bob Peppler rents sleds in west. He will deliver also to west and island park. his #406-640-1104 We have rented from him for 5 years or so. have fun
