Ok I will start by saying I found my cat was plugged....Ok! that was fixed Cough Cough! Ran much better now...Ok now for the 2nd O2. Started looking at ways to fool the sensor..Did some research on it and found a couple ways..I don't know what is right or wrong..I'm a try it and see kinda guy sometimes... So if you buy a spark plug non fouler dorman 42009 at advance.( Same Thread as O2) Take it drill it out to 1/2 on the inside of it then install in the rear. Suppose to take it out of the stream enough that it just reads enough to work...I don't know if it works or not for sure. I can say that when I did that that it idled ruff and was acting all weird like it had a bad throttle position sensor... So I was messing around with it tonight and seen my fuel pressure was looking high..Like 65psi....Took and adjusted it down and it started running worse...Go figure! So I said heck with it and started turning it up and wala the miss went away. Now did the miss go away it is unreal the crispness of the throttle! Rediculously better! I mean WOW! Woke it up!!!! Can't wait to run it on the hills! So who knows but I do know this is the best by far that it has ran since I got it!

Chime in! I just wished I had a way to compare it to another one!

Ok well Going away over the weekend but I will be checking for updates! Have a Great Memorial day! Oh yeah check out Templeton Pa of Youtube....I gotta go there...Someone here is from there but it escapes me at this moment of who...LOL Sorry....

      2021 Hisun Axis 500 No Start - Need Help Please
      By Hunterman22
      2021 Hisun Axis 500 UTV (From Lowes)
      Will NOT START
      MY apologies if this is to much info just wanted to give yal the most information possible for help.
      I'm a so called diyer. An Electrician by trade 21yrs. I got my S×S from my last job. The contractor purchased this S×S for this specific job brand new, from Lowes. They used it for hauling materials, tools, & a little bit of anything you can think of on an Industrial type job site. 
      I remember getting on the SxS one time & pushed the gas petal all the way to the floor & SxS had very little power. 
      So anyway ,when the job finished up back mid July this year (7/2024) , I asked the contractor what they was going to do with it. I was told to take it. Otherwise it would go to the contractors yard (storage yard) & most likely rust away. 
      Took it home washed it , it had a heavy coat of dust on it & in it dust was every where. My helper & I had to push it on the trailer to get it home.  After washing it throughly I let it sit & dry out for a good day and half, maybe 2 days. Before trying to start it. NO START. Will turn over & try to start but thats it. 
      So here's what I've purchased & installed. New Air Filter, new spark plug, new air idle control valve (AICV), new throttle position sensor, new throttle body, new oxygen sensor, new digital dash speedometer/fuel gauge/clock. 
      Also drained the old oil & gas & replaced with new oil & 93oct. gas. I should probably mention that I've changed the AICV twice. The 1st time I changed the AICV I was able to get the SxS started & let idle for at least 10-15min. Drove out of the garage, with very little power,  turned it around & barely got it back in the garage.That was the one & only time I've been able to start the SxS. I've also cleaned the Throttle Body and & intake with TB cleaner.  So after that the AICV was  making weird noise so I pulled it out & tried cleaning it, pretty sure I messed it up. So I purchased a Throttle Body that came with new AICV & TPS. Still NO START.  I've checked the fuel pump & the fuel injector.  I took the injector off still hooked up to wiring & turned the key over, the injector sprayed a lot of gas out kinda the size of a volleyball. I've also checked the clearance gap on the intake & exhaust valve. But today 11/2/2024 I'm going recheck spark plug gap & the valve gaps. And alot of other checking. Would the driver side seat belt have anything to do with it not starting?? I know the driver side seat belt has to be in gauged for full throttle "going fast". Thing is the drv. side seat belt will latch but feels like might be messed up inside of it. Tired opening it up but to no avail.  I've never had a S×S or 4wheeler so I was really excited when I got the S×S,not so much anymore.  I work on & fix my own vehicles usually no problems.  But this SxS is kicking my ass.
      So if possible & someone could help me with some ideas or tell me what Im doing wrong or did wrong, I would greatly appreciate it.  Thank you for reading thus far.

No luck finding this from Artic Cat or the many numerous online vendors. Any info or resources wil be greatly appreciated !

      Now that I have done the LI-Ion batt conversion, I need to do something about the suspension
      By Kingfish
      The conversion took about 350lbs. off the vehicle.  It never rode great, but now I feel every  crack in the road.  I have backed off spring compression nut to the point just under where they would move around if suspension was at full extension, but it is still very stiff.  I would like to put some softer coilover springs on it, but I have no idea what the spring rate is with the original springs so I would just be guessing on what to order.  Does anyone have the data for the original spring compression rate?  I am willing to give up a little ground clearance for a softer ride. Right now when sitting still the rear suspension is at or near full extension and the rear tires have several degrees of camber which will cause uneven wear if allowed to continue in this state.
