Hi All,

New here, but bought a 2022 Sector 750 brand new last march (old stock up here in Canada)

It's a good bike so far, but I have noticed a quirk and was wondering if anyone else has had a similar issue?

 

The issue I've had is if I leave the utv parked on any incline, not even a major incline, and leave it to sit for a while (day or two) it will not start properly. It will turn over and not fire until I press the gas pedal, when it will run and rev up, but if I let off the gas it will die. It will keep doing this until I either start it in gear and drive it for a bit or leave it in neutral and roll it down the hill to flatter ground. where it will have to sit for a while. 

If I park it on a decline there is no issue. fuel is not low, it's occurred a couple times now. 

 

Any thoughts on the cause of this? Dealership just says bring it in and let them take a look, at my expense of course.

I would check for fuel contamination, water or too much ethanol in bottom of tank. I have a Hisun tech coming Monday to check my 2022 sector for that condition, mine loses power going up my long-inclined driveway.

Well, it was interesting to watch the road tech replace EVERYTHING;  the fuel pump and sender assembly, new fuel lines, fuel filter, Injector, HEGO, TPS, and IAC. One thing he was talking about the most is water/ethanol contamination, which would settle out to the bottom of the fuel tank when parked for a day or more. Once driven it would mix in the tank and the severity of the problem would go away. He looked in my tank and really didn't see this in mine, although there seemed to be like water marks in the very bottom of the tank. He wiped it out and then filled it with premium fuel that has no ethanol. My running concern has gone away, and the unit runs really very nice now. Of course, having that many parts replaced is like a shotgun blast, hard to miss. I did end up with another electrical problem just before this last repair. it was supposed to have been fixed and was not! It is intermittent short in the main loom, (the engine loom was already replaced for another issue.) When driven on the road about 1 mile the fuse for the signal lights blows. Have no brake lights or turn signals and causes feedback in the instrument display. Hisun picked it up yesterday to take it back to Texas to replace the main loom that was supposed to have been replaced 3 months ago.

So, I guess the bottom line is check for fuel contamination. Do not use fuel that has ethanol added! The fuel pump retaining ring on the tank is really tight, watched the tech bust a sweat trying to get it off then back on, he was a very BIG dude and was using a very special tool.

You might try to get a gas sample after letting it for a couple of days in the position that gives you the worst starting problem, check for obvious contamination and then google how to check for ethanol in gas. If you find any fuel issues, make sure you replace the fuel filter. 

Hope my ramblings help you.

      Information on 2024 Hison 550x Stryker with a No start Issue
      By KWinTX
      I just bought a new 2024 Hison 550 Stryker 2 months ago. this is the second time I have had this issue.  It only has about 20 hours on it. The last time it happened we took it back to the dealer. it was a fuse.  Since we live three-hour time driving there and back. I would like to find another solution if possible.  I have tried all the fuses that seem to have anything to do with starting.  Currently checking the battery. The battery is new. it came with the unit. It is probably 6 months old.  the UTV has all power to everything electrical. lights turn signals and radio all work.  When trying the key to start . it is 100% dead. as in it doesn't even click.  There is a low whirring like the fuel pump is turning on though. The Unit was running and driving just fine.  we shut it down for the night. The next morning my wife found it in this condition.  Thanks for any Ideas or solutions???   Otherwise, it goes back to the dealer tomorrow. Just hope I didn't buy a lemon. Great little UTV when it does run.😅  anyone else ever have this Issue..?

      Is the cam sprocket a bolt removal or is it pressed on? Dang bolt is on tight. Impact wrench won't even move it.

      2022 t-boss 760 oil filter
      By Aaron Colona
      Just bought a brand new 760 about a month ago. I'm at 20 hours which the book says is when you need to change the break in oil. 
       
      I must be crazy, but I can't find the oil filter. I've googled a million videos...everything seems to be 2019 or lower...and/or a 550.  They all show the filter easily seen by looking in past the rear passenger tire on the engine. There is absolutely nothing there on mine. 
       
      1.there seems to be very little info if you Google a 760, or anything Massimo newer than like 2019. 
       
      2. Does anyone have a current model year 760 that can answer my riddle for me?

      Glass Honda Talon windshield adapted to Hisun Sector
      By HighSon
      This mod is not for the fainthearted, as it requires some basic metal fabrication and welding skills.  But the result is worth the effort IMO.  I chose an aftermarket Honda Talon windshield based on economy, size, and construction (aluminum frame, DOT glass, folding, windshield).  It fits OK, a little narrow at the top, and you need to incorporate the lower section of the original acrylic windshield and build some additional plates, but better than being too wide.  If you are wondering why I attacked this mod, it's because mine is driven daily on the street.  Tired of fading, scratchy, hazy plastic.  Sucks in the rain; sucks at night.  Now I can see.

      Hisun Sector e1 Battery replacement: any tips?
      By didgeridoo
      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!
