Polaris Ranger 570 Starts and dies

I’ve heard they can stick.  Usually more so in winter.   But not likely your issue.  


Have you checked your valve clearance?   That will make hard starting in winter, but potentially make any vehicle run wrong.  

My Ranger 900 was recommended at 200 hrs and/or 2000 miles.   I checked them at 250 hrs and had 2 of the 8 valves barely out of spec.   Hard to start, little rough idle and would occasionally die when at idle but would go down trails fine once on the gas.   Once back in spec, runs perfect, starts perfectly and idles great again. 
 

sorry, started to talk about fuel pump   But you changed it, so I removed that comment   
 

check your valves?  How many hours, miles?  
 

just throwing out some ideas.  Hope they help.

      Hello, All!  I've decided to replace the traction batteries in my 2018 Sector E1 with a 48V Lithium set. They may be expensive, but I figure the Discovery Dry Cell are, too. I am not looking for the max driving range, as I have never received near the brochured range to begin with, but a good mix of charge/ get work done/ charge is what I am expecting.
      I have settled on the 48V EAGL kit from bigbattery dot com. Each battery pack provides 30Ah. The kit ships with a charger, as well. The packs would be physically connected in parallel (using a busbar) to one another, maintaining the 48V voltage, but together would be able to provide the amp draw the buggy pulls when going up hill or towing a rake (rated 320 max continuous Amps). This is in comparison to the serial connection the eight 6V lead batteries. Each of the EAGL batteries looks to have its own BMS; am I correct in thinking I will have to use their included charger rather than (simply) changing the onboard charger to lithium mode? The chemistry of the pack is LiFe PO4, for what it's worth.  I haven't torn anything apart yet (to diagram), so  I am not sure how the dash will interpret the AMP draw, but the kit I am looking at includes a dash mounted charge indicator.
      If anyone has completed a similar conversion, do you have any tips? Specifically, how did you remove the original batteries, and how did you secure the new ones? I am guessing that almost any change from the stock batteries would involve at least some modifications. Any tips would be appreciated, especially things I may have failed to consider. Thanks!

      Cleaned fuel filter and am replacing mechanical fuel pump. Unbolted but can't get fuel pump out. Shaft sticks out and fuel pump hits axle and won't come out. Anyone had this problem?

      **Disclaimer: Yes, I know Polaris and Kawasaki are SOOO much more better, reliable, retain their value, not made in China, etc. I need a UTV and don't have the money or financing for one of those units, so let's keep this discussion productive please**
      Hi all, learning about my new T-Boss 760 from TSC, and am trying to find the actual dip stick to check the oil, funnily enough.
      Does anyone have a picture of it or something? It's crazy that I can't find it...yet here I am.
      Also - any advice on oil? Manual says 15W/40 "SJ" but I'm told the SJ spec doesn't exist anymore.
      Gentleman at TSC said to use any 15W/40, but I'm very nervous about causing an issue this early on by using the wrong oil.
      Anyone have advice?
      Thanks!

      Spent today at a Honda dealership looking at their 520 side by side, then on the way home past our Lowes noticed they had several new UTVs on site, so we U-turned and ducked in there. We were impressed that all that came for $9,999 metal whole length skid plate, nice sized bed, roof, windshield, side mirrors, winch, upgrade looking tires… all of which would have added thousands of dollars to an already expensive Honda 520. Now Honda does have a great reputation from my trusted UTV experienced buddy, so it has that going for it.
