Woow...very informative indeed. I have same clicking noise problem with my motorbike but the difference is that my engine is pretty new. I therefore think it's a timing chain issue.
Nice diagnosis. I had a honda 400ex that my son used to jump some tracks. Hit the bottom of the case on the engine and blew a hole in it. All the oil had came out. Because of the location of the hole, the whole engine had to be taken apart right down to the transmission. I have a short vid of it after it was put back together and I was just testing it. I'm more into motorcycles now
Thank you for the thorough video and also explanations. I myself currently have the exact same slap on my yamaha tt250. After valve adjustment and cam chain check i still have a slap. Next stop is to check the connecting rod and also specifically the piston slap. Thanks again for the video.
A lot of times valves do tick as well when adjusted its pretty normal. The saying goes ticking valves are happy valves lol. Because it never tick before and when i adjusted them it was a slight tick.
Great video! I was able to learn a lot. Did you ever do the video on adjusting the valves? I'm far from an expert, but own a few ATV's and would like to learn how to adjust the valves.
Thanks! I just posted a followup video of how it sounds now - tried to have some fun with it lol! ua-cam.com/video/NOy9mL4k2oE/v-deo.html A valve adjustment video is in the works as well.
Pretty sure the timing chain tensioner needs to be set every time its installed Needed that on my bayou 220 Having issues with my '97 Kawasaki Prairie 400 4x4 making noise
@@liveandletlive2894 Not a totally rookie move, you do have to reset it to a specified amount of teeth out, then manually turn the engine over a few times to let the CCT set itself. When an automatic CCT fails you will not see anything wrong with it, it's the internal spring that has weakened, so it then does not have the strength to automatically adjust as the chain wears down, or when you have reset it.
Yes, motor is running great! Wiseco piston kit took care of the slap/tick and seems to have a little more power now too. : ) I should try to make a followup video of how it sounds now.
Awesome video bud you saved me from selling my bike. Just pulled my top end and have the same issue at 260 hours. Not sure if that's common thing for these atvs at those hours but am sure glad it wasn't rod knock. What wheel set up are you running?
Nice! Glad it was helpful. The tires are ITP Mud Lite XL's mounted on some ITP wheels. The tires hook up great in dirt / mud. A little loose in gravel but good enough, but lousy in deep snow.
Did you ever finish putting it together and did it take care of the noise sorry I didn't check all the comments to see if you answer that question or not.
Hi I have a quadzilla rs6 X6 and only when I break with rear breaks my quad makes a noise like something is slipping like engine of drive it's an auto any idea mate
what about the bottom rod bearing ?? im getting a knock only under any acceleration. I stopped running it, Im going to take apart the block to investigate the piston. Picked up a spare engine in parts with a good top end for spare parts.
ya seems like rod/crank are bad there too. Its a crazy process to do the crank on the 660 and 700 motors tho. Usually more in labour than the motor is worth.
Sorry about the dog barking in background. He loved chasing the four-wheeler and would get excited whenever he saw it out.
The knowledge got my view .. the A-Team music is what kept me interested

Thank you for a great explanation with this video.
Did you ever do a follow up on this video/issue ?
hey bud wheres your next vid, did you fix it?
A lot of times valves do tick as well when adjusted its pretty normal. The saying goes ticking valves are happy valves lol. Because it never tick before and when i adjusted them it was a slight tick.
you got fourwheel back together did dat fix problem

A valve adjustment video is in the works as well.
Thanks for the information !! 👍
Did that fix the issue? I just picked up a rhino 660 sounds like the same noise.
Very good thanks 👍
Some gear tooth stripped out on my kodiak 700 crankshaft. I got it fixed tho with some welding and filing
Did you have metal shavings in your oil?
Yes, there was very small particles, looked like glitter.
Did yours smoke any?
I’ve got the same noise but a massive loss in power. It will barely pull off. Any suggestions?
Pretty sure the timing chain tensioner needs to be set every time its installed
Needed that on my bayou 220
Having issues with my '97 Kawasaki Prairie 400 4x4 making noise
On this motor the timing chain tensioner is spring loaded. Only needs adjusted (more like backed off to reset) if chain is removed / replaced.
@@ModernSurvivalists 😆 can't believe i wrote that back then. Rookie move!

Thanks bro. I had the same problem on my 2008 polaris sportsman 400 H.O.
Did you get rid of the ticking at all?
Yes, motor is running great! Wiseco piston kit took care of the slap/tick and seems to have a little more power now too. : ) I should try to make a followup video of how it sounds now.
@@ModernSurvivalists did you end up doing a new crank ? or just piston and cylinder head ?

Hi Teresa how are you?
Did you ever finish putting it together and did it take care of the noise sorry I didn't check all the comments to see if you answer that question or not.
Yep, rebuilt top end and has been running great for last several years.
Is there a way I can send you a vid of my bike? I have a sound similar but not as loud on mine. It’s a 2020 renegade 570
I think i might have the same issue as that looks like a days work but like you said 200 dollwra better then x amount
Was the cylinder still savable
Yep, I was able to hone out the scoring. This was several years ago and it's still running strong.
Sounds like your clutch has come slack mate!! I had the experience on my 150 gy6 scooter thought it was my big end bearing! Case closed
I have had several people mention that. In this case it turned out to be piston slap.
Im having the same kinda sound, any chance you saw aluminum glitter in your oil?
What did it end up being
I do and it’s doing the same noise what was wrong with yours
Hi I have a quadzilla rs6 X6 and only when I break with rear breaks my quad makes a noise like something is slipping like engine of drive it's an auto any idea mate
Damn thanks! My raptor 660 is doing the same noise but wayy much more quiet
Same here! If you read this, was it your timing chain?
@@LifeofAedan did you figure it out
if there's no smoke to your muffler the block is still ok you need to change the piston and piston ring. and pins
what about the bottom rod bearing ?? im getting a knock only under any acceleration. I stopped running it, Im going to take apart the block to investigate the piston.
Picked up a spare engine in parts with a good top end for spare parts.
Rod

Rod bearing 😢😢
YOu could have just left it & taken it to the County Fair & entered that fourwheeler into the demolition derby.
First problems is a yamaha
lol only the most reliable off road machines ;) but hey i guess they are wrong
