Hello Guys! I have purchased a 2009 T2 from a member here and it has a issue with it...It will not rev fast at all and it acts like its out of time. I checked timing and it looked good. I tried putting my scan tool on it but it says failed.... I'm pretty sure its a sensor...... The plugs are black coated. If you mess with the fuel pressure it helps alittle but I know thats not the problem........Thanks in advance guys...Oh yeah what engine is this modeled after for parts like the sensors?

I would check the oxygen sensor in the exhaust. You could try switching the two sensors but that requires swapping the plugs which wouldn't be too hard. Also look at the map sensor in the intake plentum. If you look on google you can find out how to test these. Your obviously getting too much fuel or not enough intake air. Check your air filter for being clean. Also replace it if it is the stock filter with a K&N filter mounted up high out of the dust area. Most snorkle them up to the roof area. Probably check the Throttle position sensor too. These are the three sensors that the computer is going to look at for determining the fuel required. Your fuel pressure should be around 55 psi. Watch your fuel pressure as you try to rev up and look for any weird stuff going on.

Ok I will check these sensors. Just lost. The filter obviously got mud and water sucked through it so I wonder if it ruined the mass sensor. Do you know what sensors or the motor is copied from? O heard Suzuki and Ford escort......?

The Ford Escort is close. It was copied form a european Ford engine that was popular for rally racing there. However it uses a standart engine computer by Bosch or Seimens, can't remember which. I would assume that it looks ofr signals that are standard fior mmost vehicles. This makes me think that most sensors could be adapted into the system and work fine but no guarntees.

Were are the marks on the timing belt to line up with the gears

There are not any marks on the timing belt. There is a mark on the lower pully that lines up with a mark or small bump on the block. This needs to line up when the mark on the top pulley is lined up with it's mark on the head or head cover. Go to JMCs site and download the manual, it shows the marks.

      Shifting issue
      By Pick a name
      The Axis 500 will not shift into low or reverse.  I have high when it should be in low and all the other places it is reverse.  The gears in the shift cover are fine and I shifted it when the cover was off and yet no change (so it can't be the shifting mechanism gears).  I t has been difficult to get it into low for awhile.  But now it is either high or reverse, no neutral either.

      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..?

      By davebuckholts
      I just picked this UTV up off of Marketplace. It needs batteries. 
      I am installing a single 48v lithium battery. 
      The on board charger, a NOCO Genius GX 4820, has a lithium mode. 
      Has anyone here used this charger on new lithium batteries? I want to be certain of the compatibility before hooking the charger to this expensive battery. **

      I got in touch with NOCO and they told me the charger is fine to use on a new LiFePo battery. 
      Nice charger. Many modes. New ones are running about $550.

      No crank issue
      By Flanman55
      2007 Hisun HS700  will not crank.  Replace the ignition switch. Same thing.  Replaced solenoid by the battery same thing. Can jump it and it starts good across the solenoid posts. Ran a jumper wire from switch to solenoid. Nothing 
       
      can anyone suggest something else.
