Just got the sled back from service chain case seems to whine could it be chain is to tight?
 
If you can access it you go finger tight then back off 1.5 turns. If you have stock muffler you have to remove it and will need a gasket.

Just drained my chain case today....what a poor process
 
Thanks Guys it is still the stock muffler I will have to remove it and adjust the chain tension I called my dealer yesturday he is saying finger tight and back 1/4 turn is how it is set and how they are setting them all is it sapose to be 1/4 turn or 1.5 turn?
to bad they did not have a drain plug.
 
I useally adjust the tensioner while rocking the driven clutch and run it just tight enough to take the slack out of the chain. finger tight for you may not be finger tight for me! Very easy to over tighten the chain. If it whines loud on decell its too tight.
 
Your dealer is going by the incorrect info in the owners manual. I don't even like the saying finger "tight". Use your fingers until there is a little resistance and then back off. 1.5 out after going to0 tight can still give you a lot of whine.
 
I have the exact issue. When I got it back from my first oil changed etc... I had the whining noise. I live over 100 miles from dealer and he said they don't back it off 1.5 turns like people have been saying. I have not had time to take the muffler off and do it myself because I don't have a new gasket. I have put over 700 miles on it since the service and I still have the whining noise that was not there prior. My question. What will happen if I run it another 400 miles or so before I can get it back to dealer and make him loosen it???? I have a trip coming up this weekend on my sled to the I-500 in the Soo and won't have time to mess with until after.

Thanks
 
Probably not good to run it any longer than you have to. Hard on chain and gears.
 
If your careful you can reuse the gasket.
I did. No leak.
Did oil change through side. What a pain! never complain about nytro again.
 
I loosened my chain adjuster it was way to tight Whine is gone now thanks for your help guys
