I'm trying to get my atv to TDC to check valves. Im attempting to do this with the engine still on chassis. Can someone tell me where I can remove a plug to ensure I am on TDC? 

Thanks

Don't worry so much about exact TDC. You can even check the exhaust valves while the intakes are open and vice versa. If you watch the intake open and then close and then watch the flywheel get to the "T" mark you are at TDC. But seriously, you can virtually be anywhere on the bottom of the cam lobe and get an accurate reading. The timing plug is on the stator cover. There will be 2 plugs. One to turn the crank and the other to inspect for timing marks. Make sure you are turning the engine in the normal operating direction (opposite the cam chain tensioner) If the tensioner is in the rear then turn the engine forward

      Just some friendly advice on new tires. Check with your ATV dealer. 
      There are so many aftermarket sites, Revco, Royal Distributing, Partzilla, and on and on. Even with their “ big sales”, my local Canam dealer’s REGULAR price beat the tire prices of the 3rd party sellers! People often assume the Dealership will cost them more, but I found this not to be true!

      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!

      I have a Harbor Freight tire changer. I could not get the tires off the rim.

      I have replaced the cracked stator cover on my non-running 2006 LT-F400F that I purchased recently, checked all the shafts vs the service manual and pics and advice here.  I replaced missing gears, bushings and washers, made sure that truth marks were all aligned properly, that the shift cam springs felt like they returned properly, etc.  IAfter installing the new stator cover I checked the transfer lever for proper movement from L-H-R and then cranked it up.  Happily, it runs and changes gears well in L,  but it will not shift into H or R for anything.  I have opened it back up and am going back through it looking for the missing puzzle piece(s) but how can I best check that I have everything right this time before buttoning it back up?

      I have Grizzly 700 that has been pretty much totaled out in a bad accident, but it will still run and drive good...
      Will this engine swap into any of the Yamaha UTV's like thr rhino and Viking 700's?
      Was just going to sell it as is for a engine for someone who needs one pretty cheap..but been thinking about getting a UTV for the family and maybe find one with a blown engine cheap and swap it out
      I already an excellent shape 2001 Big Bear 400 4x4 for us..but kinda been looking for a good used UTV for us and the grandkids on our property to play with
      Not sure of the year..i can't remember what year it was when i picked it up for a buddy a few years ago..he went to jail after he totaled this thing and told me to pick up a few things at his house he was renting and just keep them for myself since he owed me a bunch of money before the landlord sent them to the dump...
      The first picture is when i went and picked it up for him..second is how it is now..frame is all twisted up and plastics are fubarred..going to sell the rims and tires.they stick out way too wide on my Big Bear
