Hello everyone, did a search and not successful. Purchased new 2017 Sportsman 570 sp and my power steering is not working. Seems to have a mind of it's own. Works then it doesn't. Dealer says there's not a fix. Thought it was just me and it being a brand new machine with 4 hours on it. Dealership said it's this model only ? Not sure what a person in this spot is suppose to do and wondering are your thoughts mite be. Thanks

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.

I have a 2001 yamaha yfm350x and it has a brand new top end, new carburetor (stopped the leaking problem and is now getting gas to it), new CDI box, new stator, handlebar switches work, off-and-on switch works, new starter solenoid (works), new neutral relay (works), ordered a new Rectifier on its way, good strong blue spark. Has compression, valves are right. Timings is right and is TDC. When I try to start it it just makes a loud popping noise like its backfiring but it's not because its not running when I push the throttle all the way and when i barly push the throttle it try to start but won't, so I'm trying to figure out what could be the problem not starting now, Getting very fustrated with this thing and put some work and money into it and it's not still not working. This is the only atv I ever had that I can not figure out the problem to get running. Need help please..

Hi, Name is Dave, I am new to the site. I have UTV 2018 Textron Stampede... cant get the 4 wheel drive to work.
I recently had blown out the fuse for the acc... while hooking up my turn signals,,, and ever since then
4 wheel drive doesn't work, I can lock in the rear,,, while having the key on motor off,, I can hear the clicking
sound,, which sounds like a relay in the rear... but when I switch to 4 wheel drive, I hear nothing. shows up on
the dash that its working, anyone can help would be greatly appreciated. All Fuses and relays under hood are
good, and under rear seat. Thanks Dave

Hey all, I work for a fleet shop and we have a lifeguard ATV its a Kawasaki brute force 650. Its back firing through one carb more than the other one and back firing through the exhaust. Starts up and idles good, once you start giving it throttle it acts as if its starving for fuel. This thing gets tons of beach sand thrown at it 24/7. Things that have been replaced are:
both new carbs, new fuel pump, new plugs.
Things that have been checked: Compression is good - in range (high end of the range) also have ohm'd the coils and the resistance is within spec in the service manual. Fuel pick up is clean, no debris or restriction there. Does any body have any other ideas what it could be? Thanks for any input

Hi everyone, I received a 98 Yamaha Timberwolf from my brother for free, and I'm working on getting it going.
I am having the following problem:
The engine is backfiring through the carb.
I have done the following to try and get the four wheeler running:
Rebuilt the carb and set the air screw to 1-1/4 turn out and the circlip at middle position 3
Replaced the coil, because the cable was loose at the coil end
Repaired the main ground, coming from the battery
Replaced the ignition switch, because my brother couldn't find the key. New switch tested good
Tested the kill switch and it tested good
New coil tested goodfor both primary and secondary coils
Pickup coil resistance is at 195, which is correct
My source coil, is where I believe the issue is. The resistance is 310ohms, and it should be between 428-523ohms
When I opened the stator housing, there was significant oil, which I have read is normal. Does it sound like I'm on the right track replacing the source coil? Could this be causing my backfiring issue? It looks like the source coil is part of the stator assembly, is this correct? 4BD-85510-20-00 STATOR ASSY

Turn on key, put it in Neutral, lights on steering column light up. NO head lights and the electric start switch will not work. Let is sit for a few hours, started right up. Sat over night and same issue. Checked fuses and they were good. Battery is giving 12 volts. Opened up the ignition assembly and it isnt getting any power it comes up as a .01 on the volt meter. Pulled the spark plug to check for spark and NO spark. Will not pull start either. Unhooked the battery checked the spark while trying to pull start it and got a weak spark.
Pushed it into the garage and it sat for 2 days. Turned the key and pushed the start button and it cranked but the spark plug wire was off so plugged the spark plug back in and pushed the start button and nothing. If you jump the solenoid it will crank over but not start. Soo confused , anyone have any ideas?

Hi all...new member here...looks like an awesome site! I searched around, but couldn't find a service manual for an 02 Prairie 650. If someone has one we could download, we"d really appreciate it! We"re needing to replace the front cylinder and head, etc. for this new machine we just bought.
All responses appreciated. Thanks much!
