I wanted to share an experience and a fix.
Headed out was following a pole line, was looking for a cross track that may take me to this speckle trout looking spot on a creek. All paths and semi paths... failed. Second objective was to reach a speckle trout lake that has been recently stocked... followed 1 trail to dead end, followed second trail to dead end.... while investigating options on foot and the quad idling it died.
It wouldn't start. eventually it did... and when it did … it was essentially a pinned idle. activating the throttle did seem to speed it up but it wouldn't knock out of the racing idle. couldn't put it in gear at that idle speed. got towed out.
when I first got the quad, I ran it off a trail and buried it pretty good in the soft snow... eventually winched out. It wouldn't start. eventually did and it was fast idling. not as fast as this last time. but still fast. it eventually seemed to settle and I got it in gear and by the time I was back to the truck was acting ok. chalked it up to the bike being at a bad angle in the snow.
My investigation last year lead to the throttle position sensor TPS. how to jumper the diag block to see the sensor position on the display,. I focused on this nearly sure it was a detuned sensor or broken sensor again this time.
I tore down the front plastic and stuck my head into the TPS area to see what I could see. What I found was that the throttle body assembly had actually come out of the mounting area (not sure what it is called). the ring clamp was loose I could move it easily. Hopeful, I tore down the air intake assembly above it (air filter...etc) removed a sensor clip and a hose.
I backed off the clamp some more and was able to reseat the throttle body assembly. put some blue lock tite on the clamp screw. When I was cleaning off the air intake assembly to ensure I dropped nothing down the intake, I noticed the underside of the air intake "box" also had a clamp. this screw was completely missing.
I went to the hardware store, bought a metric replacement (brought clamp with me), seated the assembly, settled the clamp blue lock tite that as well...
quad fired right up, idled normal, idled up without hesitation and dropped right back off. Cost of solution $3.87 CND for a pack of 5 metric screws. moral of my story was don't assume an idle issue is a throttle position sensor problem... there are a number of other factors including air pressure, which I believe was my issue.
hey everyone , merry x-mas to one and all , I have just have to had my shocks and springs replaced on my 2016 POLARIS SPORTSMAN 570 , it was riding really low and did not know that was the problem, it only has 2000 kilo`s on it. anyway this time I got it done on warranty , I now have the rear springs set on number 4 to help the shocks and support the load, mu question is does anyone know the spring rate of the rear O.E.M.. SPRINGS, I am toying with the idea if this happens again to get s some what stiffer spring , but have spent hrs. trying to find info ,but no luck, trying to find new ones is no problem high lifter states that their springs are 25-30- % stiffer which is the area THAT I AM THINKING IF I DO REPLACE THE O.E.M. . any info would be great
It's time to replace the shocks and struts. Looking for some stiffer springs than the OEM as I use this for farm work and I put heavy loads on the rear and haul small trailers frequently. I've seen a couple aftermarket offerings that say they're 10% or so heavier duty. Any other options for something a little stronger / stiffer? Thanks.

Ok I've finally done me research and got my products on amazon for my polaris scrambler 500 2x4 it is a fast bike to begin with but i wanted to improve throttle response and ad a little bit more power to the bike also bought other stuff for riding like stuff to improve the quad not just parts accessories to so I bought...
FMF POWER CORE 4 MUFFLER-$205
K&N AIR FILTER-$33
K&N AIR FILTER SCREEN-$12.50-$13
SANDPAPER TAPE FOR EXTRA GRIP ON FLOOR PLATE-$13.04
LED LIGHT BAR 7 INCH -$30 PLUS METAL FOR MOUNTING SO ABOUT $40
TOTAL UPGRADE COST=$357.04 after clutch kit -$190 = 547.04
This will add better throttle response and ad more power and with the k&n a little better fuel economy I got the handguards for protection from cactus trees tree branches flying rocks mud and cold air you know the everyday riding awareness's / watch outs (EVERYONES WITH A POLARIS SCRAMBLER THIS IS THE STUFF TO ADD OH AND ADD A CLUTCH KIT WELL WORTH IT
So I got my tax return and dupmped about 2k into my LTR. The list of parts incudes a Precision steering stabilizer, stage 1 Hotcams, Tusk a-arm guards, Armadillo swingarm and chassis skid plates, Lexx MXe pipe and fuel controler, Pro-Tec Moflo airbox lid, ITP Holeshot GNCC rear tires, and Skat-track Edge 8 paddles on matte black G-force XC 10X8 wheels. The paddles will fit all my quads so they aren't just for the LTR, but I plan on buying some Skat-track Haulers for my 500R, so it won't have to share anymore.
I am sure you have all seen a stock LTR 450
This is the machine all stripped down.
