Tonight instead of removing the little plug to loosen the Allen bolt, I removed the 3 screws on the side and well.. It is in a few pieces now. I’m not sure where the little ball bearings go?? Does anyone have pictures, or anything for me?

Picked up this bike for 500. Had a mr gasket electric fuel pump on it, and flooded out when running. I ordered a replacement stock pump, installed it but the inlet is pretty much right on top of the petcock.

So…. it looks good as far as mounting based upon the PDF of the service manual, but something has to be wrong.

Thoughts? Idea’s? Suggestions???

Thanks

I have a 2003 Trail Boss 330 that I bought my daughter. It was running great the all of a sunden it started acting like it was running out of fuel when she pushed the throttle. still Idles great but it will bog and backfire through carb when giving it gas. I cleaned out the carb (4 times) new spark plug and fuel filter. Swapped pump with a good running atv. swapped coils. I am at a loss. Any ideas>

General question for ya, read manual but need clarification, what interval do the front diff, tranny, n rear diff, gear oil need changing?
Machine is 2 months old so should be good, like to keep up on maitanence!
2016 Sportsman 450 ho

I have a 2004 Polaris Sportsman 700.My issue is that it won’t idle and after riding the machine for about 15 min. the pipe gets cherry red at the head and it sounds like the donut is gone but i just replaced it about 10 hours ago. Also it spits and sputters at low rpm up to 4000 and after that it smooths out.

I have a 09 polaris touring 500 efi , I cant access the diagnostic mode and the machine does nothing when you turn the key, the fuel pump doesn’t engage and no clicks . The main instrument cluster does come on but that’s all. Before parking in garage I did have trouble starting but eventually ran fine and backed into the garage. My question is does it sound like the ECU need replaced?
Thanks for any Help.

I have a 02 Polaris 700 Sportsman 4×4..After riding awhile it will just shut off..loose everything..for about a minute or 2 then it will crank right back up and run fine..I have replaced all ignition and plugs and cannot figure out why its doing this. Any ideas anyone?

Recently my 570 has been stalling quite often while plowing usually when i let go of the throttle in reverse and sometimes i would get a rough sporadic idle. What could this be? There’s fresh gas in the tank and all though the spark plug had some carbon around the edge the tip was clean and dry.

Hey Guys, I just posted this in the Sportsman forum but thought I would link it over here. Please take a look and let me know if you have any suggestions!

Thanks,

John

I have recently acquired a 2006 Sportsman 450. The ECM was replaced on recall in August 2015 (previous owner, confirmed by dealer). As luck would have the NEW one also crapped out. The internal voltage regulator, inside the ecm of course, is not working and battery over charges to 18V at 3000 rpm+ (tested with meter)

My question is, has anyone tried to put in an external regulator between the stator and ecm or between the dcm and the battery to regulate the voltage going to the battery? The ecm is $150 retail and regulators are cheaper than that.

I have a new ecm on order at dealer, but I am curious if this would work.

Thanks for any replies and advice you may have to offer!!!
