All the timing chains I have seen in a SxS are just like that so it doesnt surprise me at all.  The reason I said possibly a stretched chain is if the steel in the chain didnt get hardened right then it would stretch.

I don't know it that is really possible with these types of chains, as I understand it each little plate is assembled after they have been heat treats, the whole chain isn't heat treated as a unit, therefor even if one of the plates was weak there what like 10 others in line with it? Not sure cant see how many wide it is from this angle.

They dont heat treat the chain links one at a time chief.  Mass quantity so the likely hood of the whole batch of "chain bits" being bad if one is bad is VERY high.  They probably heat treat 5000-10,000 at a time. and only a few hundred are used in each chain.  So if 1 batch got messed up then like 500 chains could be bad.  Now that is a overall low percentage of chains.  But its still is a problem

What's to say the chains are assembled right after the links are heat treated? Doesn't matter, even so, that is one tough ass chain on a 60hp machine running a couple valves I highly doubt they have a failure of a chain due to heat treating with the low level of torque put on these. I mean if anyone has one of these chains that actually stretched it would be neat to see but dude, you don't think that chain is overkill? They don't run chains like that on any automotive application I know of.  Just saying I doubt there is an stretching of the chain going on here.

Sent the pics to CFMoto tech service.  He responded that the chain did not look right.  He did some research and apparently the earlier models (such as mine - 2015) had an issue with the chains binding and jumping teeth.

They usually fail around 500 miles,  mine has a little over 500 miles on it. 

So how hard is it to change the chains and sprockets?  Sprockets are pretty straight forward.  I am worried about the chains.  Would it be easier to pull the motor and do it, or do it in the SXS.  Tech rep said it can be done in the SXS.  Would it be easier to pull the motor and do it? 

Just when I thought it was fixed... :-/

Well, personally I would try to so it "In Frame". Although I have not done one of these yet, chains aren't too bad usually to do. Grab the manual, think Chinese, and go for it.

Looks like you were almost there already,  maybe have to pop off the bottom sprocket then they pull out the top? I've never seen the engine apart,  sorry i can't help much.

I have had a few stretch on me. it happens all the time. The tensionor takes up the slack on it's own until it can't any longer. You will have to pull the stator cover and remove the flywheel with a puller. Not sure of the thread size on it. Motion pro has a bunch if you know the size you need. Once that is off, slip the chain over the crank and fish it up to the cam. A long bit of wire with a hook works good. I would replace the sprocket too just to be safe.

If you can do it in the frame then do it in the frame.  I would imagine that those do not have a master link that you could use the old chain to feed it down through ...that would be to easy LOL

[NMKawierider]

Yeah..no master links on timing chains

Ok I stand corrected. I am amazed this type of chain stretches being used as a timing chain.

I was thinking the same thing.... lol..

The chain did not stretch..  There is an issue with them binding and not rolling smoothly,  that is when it jumps...

CFMoto was nice enough to cover the parts due to the low mileage of the machine. 

[REDRIDER]

That's cool!

[NMKawierider]

Good for CFM...glad they covered the parts.
