I purchased this four wheeler used a few months ago. ran excellent but recently brought it to a mud bog and gave it hell all day long. Towards the end of the day it developed a ticking/knock sound upon heavy acceleration which eventually clears up. i can almlost feel it between my legs. it does it more if i gas hard in a higher gear. Still starts up fine, seems to have good compression, enough to break your ankle without using the compression release lol. it doesnt smoke at all and does not seem to make this noise im neutral. only under load. does this sound like a top end issue? piston? valve clearence or valve train? timing chain? or possibly something with the clutches. Im a little stumped where to start. Maybe if someone could suggest a step of tests/procedures to diagnose it would be helpful. All input is appreciated. thanks

Check the valve clearance, as well as the cam chain tension. Those are the two that pop in my head first, as those are the first two that will give you "ticking".

Now once I was on a poker run.. and I myself had a very loud ticking noise.. turned out it was the cam gear bolts backing out, hitting the valve cover!!!!!! Found out they should have lock tight on the threads!!!

Thanks for your input, i will check as soon as i get home from work and chime back in with my findings. However would this explain a loss of power during that tick/knocking occurance. it will get going if i ease on it or it will eventually clear up but while its ticking it seems like it has less power. maybe more towards valves then? thanks

Almost sounds like intake leak, or cv axles...Its just interesting that it doesn't do it in Neutral.

quick check is to see if your cam chain is stretched. pull the tensioner, with the arm extended all the way out try installing it into the cylinder. it should not fit flush. if it does, it needs replaced. that can cause a bad tick.

other then that, pull the valve cover and have a look. that'll pretty much give you any other indication.

my guess would be you overheated the engine ruining the rockers, along with possibly cam and cam journals.
