Actually when you crank a ATV engine the crank is connecred from the starter gears assy so if the chain is broken, the piston compress and succion in and from the cylinder head that there is no valve cycling. If there is no compression some valve are bent or worst piston may be cracked. Imagine a syringue, try to push and pull while keeping the outlet/intlet close.

Also my chain is stuck in the lower case now. A good builder over here told me that on can-am they use a manual
Timing chain adjuster to avoid slapping. This way they report less breaking. ???? So as you stated hiperf cams springs need special maintenance for the timing chain when it's hight revved most of the time. BTW I had about 300 hours on this chain.
Thanks for your reply :-)
Built, reliable and hard trailriden!
