Video of engine noise!!! Help please!?

I have a 2005 Polaris Sportsman 500 HO. I heard this noise and replaced the starter bindex thinking that's what it was. Sound continues even after new bindex.

Video here https://youtu.be/E7TFCpvb3UI


I'm hoping it's not any better end work, but if anyone recognizes this sound, please help me save the time. I plan on tearing apart the engine, I'll do the bottom half if I have to.

Also, it is worth mentioning that after draining the oil to do an oil change I found that it has a slight hint of milkyness to it and clearly a head gasket sealer applied to the oil from the previous owner.

(new to me) 97 sportsman 500

cheers all - just picked up a 97 sportsman 500. seems in good shape, speedo doesn't work, and left front wheel bearing has a bit of play, and primary clutch rubs on housing/cover at idle. other than that its near mint. winch, vampire tires, etc etc.

so i'm just wondering what i might be looking for, as i give this thing a once-over.... any common issues i should check out? any known issues that i should address even before they become an issue? funny thing is i worked at polaris dealership when i was young, in the late 90's..... and i remember when this sportsman 500 came out lol.... man it was a game changer. at the time a kodiak was the big thing, and i remember i'd take our demo sportsman out and launch it up and off the snowmobile loading ramp we had built, smooth landing, wouldn't even spill your coffee if you had a cup holder lol, not so much with a kodiak. anyways i was gonna buy a grizzly 700, as they are quite proven, but this sportsman popped up for sale and i just couoldn't help myself. did some review reading, and of course the consensus would be to buy the grizzly, which is why i suppose i bought the polaris lol. anything i need or should be concerned about before i venture out into the mountains?

2010 Sportsman X2 Clutch ?

I was looking into a clutch upgrade for wifes 550 x2 on the RVS website. The kicker is for the 2010 year only, there is a extra $130 tacked on for about a $395 clutch upgrade .

I have a RVS clutch spings/weights in my 800, and it works great. But, not really wanting to drop $400 on hers right now. It works ok, just takes a little extra gas to engage. Any other springs I could try? I am guessing it is a little more harsh because it is meant for 2 riders?

So, any cheap upgrades to try in the mean time? Thanks.

Oil in stator cover

Hi guys. After 14 thousands kilometres and 400 mth, in my SP 500 Touring 2010, I first time took off right cover. I want to change bendix, because sometimes it is not starting from first time.
I found some oil there. Should I change oil seal?

2016 polaris 450 HO

Hello Folks,

New to the forum and I'm looking for answers and confirmation. I am working on a 2016 450 HO that has some starting/running issues.

It will start, though it is hard to get it to start and it will run, spitting, sputtering and backfiring all the way. Here is what I have done...

Replaced fuel with non-ethanol fuel
replaced spark plug
removed and cleaned injector
charged battery

Here is what I believe to be the problem at this moment. I removed the spark plug to check for spark. As I was holding the boot and placing the spark plug against a metal surface and turning the engine over, I got charged... That tells me that the boot is leaking spark, right? Or is there something else I am missing.

Also, I'm told that the bike was running and then started running rough to the point it would run anymore. When I got ahold of it the battery was low. Battery isn't very old and is charging as I type this.

Thanks for any insight.
