2013 500 HO Top end replacement!! :(

Recommended Posts

Hey guys,

Just got my new 500 HO a few months back and after a ride the other day there was major banging from the top end. Brought it to the dealer and they had a listen and said its coming from the top end. The mechanics hauled the engine out and had a look in and said that there was major scoring on the intake side of the cylinder and the piston was damaged causing "piston slap." The mechanics said they have never seen anything like this on a brand new quad. There is 400kms on my bike. The bike has never been drowned in water or any major incidents on it. Its basically lady driven. My 500 is under warranty for the fix but im trying to pin point what exactly when wrong to cause this. Upon further inspection of the bike, there was oil pooled up in the air box that mechanic said it could have been sucked up there from the bike being rolled over or being on a steep incline for too long. Which it never has.

Ive been reading around and people were saying that a faulty oil pump could be a issue. Is there any way to prove this? Or to test that in fact that it is broken. Is there any other thing that could cause a top end to go on a new quad?! I'm boggled here. I'm worried that it will happened again after the dealer fixes my problem and I'll have to pay out of my own pocket. Thanks in advance!

      Problem: The ATV starts and runs at idle perfectly. But as soon as I open the throttle, the engine starts to slow down until it stops. On the attached video you can hear the sound of how it works: see video below
      Prehistory: there is a Polaris Sportsman 500 1998, which for about 1.5 years stood in repair, including also replacing CDI with one taken from the same ATV. Finally, the vehicles were on wheels, traveled several kilometers and overheated - forgot to fill the antifreeze Came back home in small moves. The next trip started well, but after 10 km there was a feeling of a small drop in power (even as the vehicle got warm completely) but still drives. Next trip - the situation is repeated. The next test of ATV through time and a huge loss of power from the very beginning. The engine sneezes, does not want to go more than 5 mph.

      What has been done: the carburetor has been replaced with a new one (inexpensive, $ 40), a new spark plug, a new ignition coil, the engine head has been removed, the piston is in good condition, valves were corrected - but the problem was definitely not in them.

      Ignition control unit is suspected. Who faced similar? Please help in solving the problem.
      Thanks in advance.

      Blows out black smoke when you rev it up how do you adjust the carb?

      My 2005 Arctic Cat 500 started leaking fuel from the top right hand side of the carb. It looks and feels that the fuel is coming from under the throttle cable housing area just above the primer pump. I have not had time to take carb off. Has anyone had a leak on this side and area of their carb?

      Does anyone on here have a 2013 honda rancher? I have had several Honda ranchers in the past but I bought this 2013 rancher and it hits the rev limiter at half throttle. It is very annoying and I was wondering if anyone else's Rancher does this. If this is something from the factory or if I have a problem or not just trying to figure it out. Any help would be appreciated
