Got it.
Just bought my first cat (2016 M8000) and have been stoked to get some miles on it, until now. Always been a pro guy , but not like those were flawless either ha
Kanedog discovers a Clutching CATastrophy, again. Pics!

The turbos and mods could be operating a few hundred rpm higher than stock. The power added may also change the harmonics or even make them disappear. The higher rpm may be out of the damaging harmonic zone. Maybe that’s why they are lasting. The mod sled guys would have to keep an eye on the clutch cover for cracking from cover bushing/spider nut interference as the clutch would be more likely to reach full shift out.
Picture harmonics like a hitting a tuning fork on a piece of metal. In a sled, this sound can happen at a certain rpm at a certain certain part of the Hp/tq curve. Kinda like a high pitched sound breaking glass but in this case, causing crazy accelerated clutch wear and possible tiny stress areas. If the Hp/tq curve location is changed, and the 7900 rpm target rpm stays the same, it may be just enough to cure the harmonic issue. Maybe not cure it as it may occur briefly be at say, 7400 as the rpm rise but not at 7900 rpm. The engine will not be at 7400 as long as 7900rpm. If the issue is completely cured, a harmonic balancer on the clutch won’t be required. One would think a quicker revving sled without a 2 lb rotating weight on the clutch would be desireable. Is there a ring on the stationary sheave as extra insurance on the 2020’s? I dunno.
The Ctec2 top end change didn’t make sense as there were no power or fuel efficiency issues that sleders knew of. If Cat was after more power to stay competitive, they could have easily made 168hp/110tq but they didn’t. Weird.
If I disappear, please investigate Textron or Team. You could even bring the story to the Investigation Discovery channel and make me famous posthumously. Haha but not really haha.
The above are my beliefs.

im going to go out on a limb and say that the Kaner has probably pissed off a lot of people so there will be lots of suspects to investigate , lol

man..with them trained beavers as body guards no one stands a chance getting anywhere near him. Failed tree fall attempt, I think not. It’s called a snare son, hooked up to some crazy unicorn clutch.

2016 is fine. Watch for premature button wear. But this is the newer style roller clutch issue.
Kane may be right about big bore or turbo sleds being fine. Ive got 2000miles on my clutch, 1500 at 180-190hp, 500 turbo, with no signs of wear. And as Kane loves to tell me, it’s a piece of s**t, and poorly tuned by an idiot.

Was also used to help with the reverse work and pull start easier. My 09 reverse wouldn’t work with the ring gear off. And pulled over extremely hard.
yep Textron probably will be sending a left over cluster bomb to fuk up that beaver dam.
My vote too is that the ring is for ease of starting. My 05 King Cat had the same thing. I took it off and what a bear to start.

^^^ this. Put a P85 on a Cat 800, and you’ll know what it’s like to pull start an M1000 with a high compression head. Any doubts. Try pull darting a sled without the primary clutch installed...

Now Im scared to ride my 2017 King cat! better checker out real close like! As if there isn’t enough ways to die in the mountains, now my own damn sled is trying to whack me.... sheesh.

I wouldn't worry too much, I've had good life out of clutches on boosted 4 strokes. That being said, a 911 cover is a cheap upgrade that adds a lot of strength to the Team primaries.

The weekend investigation update is upon us.
As we know, 2020 Ctecs come with new cylinders, pistons, head, different injector placement and...........................
a new flywheel. Hmmmm. Why a new flywheel? Harmonics issue perhaps?
In other exciting news, to find out if harmonics are affecting your sled, check the bolts in the picture below. If they are loose, it is an indicator of an issue. Those bolts are integral parts of the sled frame/structure fyi.
Regardless of the outcome of this deep, deep, super deep, really deep investigation, I really like my sled. I would not sell it, trade it or buy another brand. I would though, accept a 2020 motor from Cat.

Textron Arctic Cat just notified me to let you know that your new 2020 Ctec 800 engine is on it's way! They also told me that they have a 2021 850 Ctec engine that they would like you to test for them in this upcoming season along with three new mountain chassis's that will require you're complete attention and evaluation in full chicken scratch writing including many diagrams. Click your heels three times to let me know so I can let them know asap. Arctic Cat is very excited and anticipating your feedback on all the many many....many issues that they have on these issues!

Haha well please notify them I said hi.
They should also know about the Federal Consumer Protection Safety Commission(CPSC). Tell them the CPSC will find out that Cat/Team knew about the harmonics/clutch issue. This knowingly puts the public safety at risk. This is when the SHTF. I’’m not even reporting my findings to any authority. Feel free to report anything you like. I’’m simply posting the evidence I find. I think this is gonna be pretty big. Like, millions of dollars big. You can’’t knowingly sell a product that can hurt the public. It’’s nuckinfutz what’s going down.
Have you ever seen a safety recall for a kids toy just because one kid almost choked on piece of it? The recall goes down big time and fast.
It’’s uncool to knowingly have customers unknowingly playing Russian roulette with their lives. Imagine a fist sized chunk of aluminum spinning at 8000rpm. Now imagine that chunk letting go and hitting a human body. It’’d kill you. What kind of a person knows about potential injury or death and doesn’t even issue a safety warning? Now that’s messed up. Oddly enough, I’m not even fired up about this. It’s just so wrong and so obvious for all to see.
Please select a cause of the following damage.
1. Normal wear and tear
2. Aftermarket part installation
3. Modification by customer
4. Harmonics
5. Vibration
6. Manufacturers defect
7. None of the above
The above are my beliefs.

KD you didn't get suicided yet that means you aren't creating enough of a stink keep up the good fight
Good pics! At least it didn't toast the belt! I remember producing a list in another thread of deficiencies including cat clutch pieces being embedded in left leg. ummmmm....
