Hard start no idle 2015 rzr 900

Here's what's new:

Spark plugs

Pedals

Fuel pump (im at 58psi exactly)

Fuel line

Oil flushed and changed/filter

Here's what is fixed/verified to be good:

Air filter

Throttle body

Valve lash

As far as I can tell, injectors are firing, but i have no way to test pattern/consistency.

Vehicle wont start without pressing the throttle in, and it just wont idle under like 1600rpm.

With that problem, and the things above, any information on what to do next would be very much appreciated.

Thanks.

Chat, am I cooked???

On a real note: is the drain plug supposed to be rounded in the center? It doesnt look like its stripped out, but i need to figure out if I need to start hammering a torx into it, or if theres a specific tool, I have no idea what that would even look like, but I know less than nothing about UTVs. I can get it out lol, but if I dont have to ruin it, thatd be ideal, so I dont have to replace it. Thanks for any input

Engine light on my new General after 5 miles

I purchased a lightly used 2023 general from my local dealer. It has ~190miles and overall looks barely used.

Once home I took it about a half mile down the street to a dirt road just to test it out now that it's home. I didn't do any very aggressive acceleration and went about 40mph. Before I could even make it 2miles it got an engine light. It gave the codes 65590 and 65591 and went into limp mode. The dealer says it's because of the street driving slipping the belt. I putted around the yard and got the light away so I drove it even easier this time down the street and it came back after a mile.

I read that belt slippage can cause this so I checked the belt and I could see what looks to be light glazing on the primary clutch. Could that be the cause? I'm going to contact the dealer again, but to me it seems absurd that just a test drive down the street would cause an engine light. ( I know excessive street driving isn't ideal)

Any thoughts would be appreciated

2015 Polaris 570 sportsman.

Is there any good replacement fuel filter to get more than 10 hours out of. And is there any aftermarket kit to cut out and install a flap door in place where fuel filter is located so that You Don have to halfway disassemble the machine to change it?

Fluid Alternatives

I have a 21 Ranger XP1000 that I'm planning on doing a service on. I've had it since new and have been reluctantly putting the polaris stuff in a few times a year, but now in between jobs, want to go good, but cheaper options.

Oil: I always have T6 on hand for my truck.

Front axle: still have a few changes left in a jug bought from polaris. But don't mind getting something else.

Rear/ Trans: I'm open to options.

The dealer near me isn't always open or have a whole lot in stock majority of the time as well, so trying to source stuff locally and soon-ish isn't always an option for OE. I've been goggling for answers and get a myriad of this and that, but for all sorts of generations and different machines. I appreciate any insight from y'all.

The machine has some hours and over 4k Km on it by now, no major work or issues. A few belts here and there, just regular maintenance for my adventuring and would like to save the cash where I can

04 Sportsman 500 help

Hey all, I'm the lucky 3rd owner of an 04 sportsman. As far as I can tell, early not mid year release. The previous owner had it pretty caked in mud, radiator was plugged, fan definitely couldn't move, etc. They said the gauge pod flashed hot as soon as you started it, the choke cable was stuck, and there was an axle issue. I stripped it down and replaced most of the rear suspension and axles, relocated the radiator and replaced the temp sensor. The radiator had almost no coolant in it so I thought maybe that's why it flashed hot immediately (I didn't realize it was *immediately as soon as it started).

So long story short it's all back together and the gauge still flashes hot immediately after it starts. According to what I found online it could be a grounded out sensor lead, and ECU, or a blown inline breaker. I don't see any evidence of an inline breaker on the fan lead. I unplugged the temp sensor and the hot warning didn't go away so the sensor isn't the issue. I don't see any relay or anything an early year 04 is supposed to have so maybe it's a .5? There's an aluminum finmed box that I assume is the voltage regulator, and another black box above that that's probably an ECU? But no fam relay, no breaker, or anything else. Direct 12v to the fan turns it on so that's not an issue.

There's no rubbed wiring harness I can see. What else might cause the immediate hot warning on the gauges? Could it just be an ECU issue?

The fun thing about taking on a 22yo quad is having no idea what's stock and what someone cut out or changed along the way.

05 Sportsman 90 - Oil

Just cleaned the carb and drained all fluids on my son’s 2005 Polaris Sportsman 90 with oil injection. We haven’t owned it for long, and wanted to do things the right way moving forward.

The ‘05 manual calls for (Polaris) VES II 2-stroke oil for the injection system, separate from the gearcase oil.

I don’t mind spending the money for the Polaris brand oil, figured I’d play it safe and follow the manual. The current VES formula on the market which supposedly replaced the former VES II and Gold synthetics advertises for snowmobiles (seemingly exclusively). I can’t imagine that’s ideal for off road riding in July.

What do I use for the oil injection system? Hoping to hear some tried-and-true rec’s. I know I’m probably crazy for even considering the Polaris brand due to the price.

Thanks in advance

Need Help: 2004 Polaris Sportsman 400 4x4 No Spark

Hi everyone,

I have a 2004 Polaris Sportsman 400 4x4 (425cc, 4-stroke). It sat unused for quite a while, and now I can't get it to start.

So far I have replaced:

  • The battery
  • The spark plug
  • The spark plug cap (boot)
  • The spark plug wire

The ATV powers up normally, and the engine cranks when I turn the key, but it will not start.

While troubleshooting, I checked for spark and confirmed that the spark plug is not producing any spark at all.

At this point I'm not sure what else to inspect. I'm looking for a service manual or wiring diagram to continue diagnosing the problem, but I haven't been able to find one that clearly matches my model.

Has anyone experienced a similar issue or have any suggestions on what I should check next?

Any help would be greatly appreciated.

Thanks in advance.

Part found on trailer question

SOLVED: Not part of the machine. It’s a piece from a ratchet strap.

Evening all.

I got back from a ride this weekend and took my 2026 Ranger off the trailer, washed it, and put it in the garage.

Today I needed to use the trailer to move stuff, and found this part on the deck of the trailer (near the front of the trailer where the front of the SxS would be)

Any idea what part this is?
