Can someone provide instructions on what needs to be done to remove the exhaust to gain access to the chain case adjustment nut? The exhaust bolts are apparent but guidance with the spring and any other hidden connections and how to preserve the gasket would be appreciated.

Chain Case
Really like the sled. Nicest sled I have ever owned in MHO
I am just waiting for more feed back. I have not seen any reports (Unless I missed it) back from anyone who can give any facts as to what the dealer said happened. Especially anyone that had broken gears. I also have not seen any reports that it has happened a second time. Most of you guys are a lot smarter than me BUT I have talked with three separate guys who know what they are talking about and they all agreed on two things.
#1. A loose chain alone will not cause a sled to jump out of gear
#2. If it jumps out of gear whether there is damage or not "It is a problem"
I am older as are most of my sled friends and I have asked twenty five guys and have not found one that ever had a sled jump out of gear.

I just finished my tensioner and 300 mile oil change, not too tough.
I first unplugged the O2 sensor, then loosened the 3 exhaust bolt approx 1 turn, then took a utility knife and ran it between gasket and header side of connection point. I then pulled the spring off of the top of muffler, loosened bolts all the way and lifted exhaust out.
For install I used a piece of electrical tape to hold the spring upright, set can in place, started all bolts and tightened, then used a spring puller to hook spring. Finally hook up O2 sensor. No sweat. I did loose approx 2" of one of the 3 gasket layers so i took a razor blade and smoothed the transition where the tear was. No leaking upon reassebly!

I think it to much to so I adjusted it at 1/4 turn out , I'm sure right from the factory they are set at 1 1/2 so that's why some are way out and turning the adjust in so much ,tensioner isn't set right at the factory !

I thought the Cat's had an automatic chain adjuster on the 7000's. So I'm guess that is for another model cat.
Nope, the 7000's have the same manual adjuster.Just adjusted mine and tightened 3 turns.

When you change the chain case oil is the gasket reusable?

Head Gasket
Head gasket from Exhaust is not. Some have used it but It does not look like it is worth trying.

Well I only have about 60 miles on mine so I thought I would check it. It took about three turns and I backed off a 1/4 of a turn. I hope that is correct. I think the problem is from the factory. I bet both the cats and the yamis were both set at 1 1/2 turns out so I would think with a manual tensioner 1/4 turn out will be correct. I hope!
