Hi,

Last winter my 98 polaris 500 ran poorly and would stall (we use it for plowing). Over the off season I did a series of improvements: new carb, oil, fuel filter, air filter, battery.

I tested it a couple times in good weather and it idled perfect. After a few laps around the property, it ran okay but seemed to missing about 5 mph of high end speed. To plow, I didn't think it would be a big deal so didn't worry about it.

A month later I got it out to plow and it still idles excellent. However, now when I press the throttle it sputters on a consistent cycle. I get about 2 seconds of power, then a sputter and repeat.

It never stalls but the power just cuts in and out.

Any suggestions? Thanks!

Been smelling anti freeze last few times out. Refilled coolant as it was low. Went for a short ride, starting leaking from overflow tube. Bubbles are coming into tank pushing coolant out.
Am going to do a cylinder leakdown test this weekend hoping it's not a head gasket.
Pumped the lower radiator hose hoping it was just trapped air, but the bubbles kept coming.
In denial still.
Has anyone else had gasket failures? Search feature here seems rather limited data base wise, so it produced no results.
Also has any one replaced the stock pistons with a better, longer skirt piston to get rid of the "normal" knocking, slapping pistons?
Facing the inevitable, ill timed, teardown I'm afraid.
PS: seems to run fine, no skipping and don't smell it in the exhaust.
Dumping the oil to check for contamination this weekend too.
Ahhh, denial, denial,denial.

I have a lock and ride front cargo box on my sportsman 550 and recently built a removable wood carry-all box to install on top. For chainsaw, extra gear/etc. Worried about is sliding around when strapped down so I decided to build a 1/4" plywood boss on the bottom of it to allow it to lock in place with the recessed pattern in the top of the Lock-N-Ride unit. If anyone is interested in the template to make one, I can email a file to print it out. I'm a NEWBIE to forum but will add pictures if I can and anyone needs a visual.

I installed a winch on my Renegade 1000 and ordered the Warn 54" plow with mid mounting plate. The plow is scheduled for delivery tomorrow but we had about 6" of snow arrive today! I did not want to shovel all that snow so I searched the web for something my son had mentioned to me.

He told me that he had seen someone use a television box to plow with. I thought, no way could a tv box hold up to that. But, as I searched the internet I quickly found a video of someone using a TV box attached to the front of his ridding lawnmower plowing a small amount of snow. :eek

I received a new 55" television for Christmas and still had the box in the garage! Could it possibly work? Only 1 way to find out!

The windshield and fairing is pretty much brand new, the bike had 29km on it when I bought it. CDN both are worth $330 + tax, I will sell for $250 CDN. More for the local people to Toronto/Guelph/Kitchener Ontario area. Thanks

I am a 2001 Polaris Sportsman 500 H.O. and when i shift into high it will sometime pop back into neutral. Is there away to just adjust the linkage to make it work or is this a deeper issue?

Weird question about my 2012 Polaris Sportsman 500HO.

When I turn the key it sometimes starts, but most times all I get is the starter clicking with a whirring sound at the starter.

I have power at the positive on the solenoid (direct from the battery). I disconnected the cable from solenoid to starter so there was no resistance for some tests. When key is turned you can hear the solenoid click. I also used a test light, there is power from the key to the starter. Power also goes to the output for the starter from the solenoid. (Solid light on test light). However..... when I hook up the cable to the starter, and and add that resistance then turn the key, the starter clicks, the light is now very faint on the solenoid at the cable to the starter.

I assumed it was starter. I removed the starter and took it to a shop for test and rebuild. They took it apart cleaned it, bench tested and all works great. I re-installed the starter and am having the same issue. When the starter was out, I looked and the flywheel on the engine portion, it looked clean and there were no rounded or broken teeth or anything noticeable.

So I know it is not the starter, I assume it is not the solenoid (unless it is possible that the solenoid is failing with any resistance?)

I even tried boosting with battery charger, thinking maybe the battery isn’t charged enough? Same thing with a boost. I charged the battery overnight (2amp) and no change. I tried another battery (it is unknown condition) but it does the same thing.

I will take the batteries in today to get them checked, as maybe neither are good?

Any other ideas???

This is frustrating, especially since the quad has no pull start for a backup

Hi
Can anyone help me define this sound. Coming from top engine.
I have turned off the valve cover and found nothing abnormal.

Hope someone can answer me.
