Ok, so I bought this atv, and after getting it home and running it for a while an engine noise developed. It was not constant but very annoying. After reading several post I thought it was timing chain tensioner and decided to tackle the job. I have the head off and timing chain exposed, but it seems good and tight. One area of concern I have, is to the right of the lobes is some piece of the cam shaft that seems to have lots of slack in it. It might be called the decompression cam. If so, is this thing supposed to be able to rattle around? If not, that may be my problem. Are there any clips or something of the sort that are supposed to lock it in tightly. Any help would be greatly appreciated. Im no mechanic but can follow directions.

      2013 outlander max xt 650 loud whirring noise

      Anybody familiar with this noise from my quad? Just started.  It temporarily goes away when I attempt to shift into another gear but shifting has gotten harder too.
       
      Thanks

      I'm in the middle of repairing damage from the chain coming off of this from the previous owner. (I learned this is somewhat common on these for various reasons.)
      What are you guys using to either help keep the chain correct and on the sprocket or guarding your engine in the case that it comes off / breaks?
      Is there an upgraded guard that can bolt around the sprocket in replacement of the currently broken OEM alluminum?

      Starter not staying engaged while cranking
      By HoldenBoy
      Hi all,
      Looking for some help on a starter/bendix issue. Can Am outlander 450 2017. While cranking to start, the starter spins and engages into the ring gear. After a few seconds the bendix retracts while still spinning and there is no damaged teeth on the drive pulley.

      Need Help with My 2021 Polaris Sportsman – Engine Stalling Issue
      By digrig
      Hey everyone,
      I’m having an issue with my 2021 Polaris Sportsman 570 – the engine keeps stalling after running for about 10–15 minutes. I’ve checked the air filter, spark plug, and fuel lines, but can’t seem to find the root of the problem. It starts up just fine, but then loses power suddenly.
      Has anyone experienced a similar issue with this model/year? Would appreciate any advice or troubleshooting tips you’ve tried that worked. Thanks in advance for your help!

      Shaft drive vs chain drive?
      By P_syko
      Which is more reliable? Shaft or chain drive?
