Riding out today it acted like it ran out of gas,  stalled and died and would not start.   Towed back to house,  New  plug added this past month,  plenty of oil, getting plenty of gas, battery cranks good.   Trys to kick in and starts but doesnt.   Two days prior while sitting at a idle it died.  Added gas and it started did my ranch chores with it.  But just now it stalled out cranks but will not start.   Tried to find if fault codes came up on the clock like manual says but not sure I am doing that right.  Any and all help apprecated.  Thank you

Fuel, spark, and compression.  They are the big three.

Fuel... when you turn the key to start (not crank) do you hear the fuel pump run for a few seconds (it should).  If so, pull the line at the injector and see if you can pump some into a can.  If so, pull the injector and crank the engine.  Does fuel pulse spray (it should).

Check compression... should be at least over 100psi.

Spark... if it has spark, is it getting spark at the right time.  To check, pull the cam inspection plate.  Get engine to TDC and mark camshaft with white paint at TDC on cam.  Crank engine and see if you get spark at TDC (i.e the white mark you marked on the cam).

Report back with findings.

      AXIS 500 WILL NOT START. HELP!
      By Frank Mac67
      My Axis 500 has been operating properly for almost a year with Zero problems. While I was away my granddaughter & friends were riding & playing in the snow. They went to the gas station to fill the tank & the vehicle would not start afterwards. I BEEN GIVING MULTIPLE STORIES: The ATV will not start. When I turn the key I can hear the fuel pump come on but nothing happens other than that. 
      - NO CLICK - NO OTHER NOISE
      *I CHECKED THE BATTERY 12.43volts
      *I replaced the solenoid inside the battery compartment. 
      Seems the next electrical component in line has battery connections IN & motor connections OUT with 2 other small wires connectedaswell(I do not know the name of this component).
      Can anyone help?
      I can not find an ordered list of electronic components starting at the battery.
      Can anyone help with this?
      Thanks in advance for any help.

      New AMP Pro Owner
      By Xov
      Just received delivery of a 2024 AMP Pro.  Thought I'd start a thread with my impressions as I use it and learn more.  There doesn't seem to be a whole lot of real-world usage information out there on this model.  Hope this will help others as they research.
      Intended Use Cases
      Fire mitigation / slash removal from a 5 acre forested and well-gamble-oaked property.  The previous owners thought as much about fire mitigation as I do about fashion: not much. Snow removal Stump pulling General hauling (rock, lumber, etc.) Weimaraner energy depletion.  Wasn't an original use case, but a nice added bonus.  Experiences So Far
      Wasn't impressed that two of the bumpers on the underside of the bed where it sits upon the frame were missing.  The metal on metal contact has damaged the powder coating and the frame.  I expect a little better QC.
      I've only put a few hours on it, so not a ton to report on usage.  It isn't quiet; it's silent.  I can't even detect an electric note from the motor. I removed (and subsequently replaced) the motor cover noticed that the motor is German and made by Schambuller.  The motor controller is Italian and made by Dana TM4.  Given the operating specs of both I found on the web, I suspect both are higher quality than the previous Navitas (which is supposed to be decent).  The motor is rated at 25 hp and 71.5 lb-ft of torque.  It feels very powerful.  All the torque is delivered instantly, if desired.
      The bed is huge and has an electric dump as standard.  Great feature but would like it to go up a bit more.  Probably not feasible from an engineering perspective, but I want and I need ;).
      Power steering is nice, but vague.  Probably common to many UTVs, but I am accustomed to more direct results from input.  Plan early and plan often.
      In our first full day of usage, we hauled about 1/2 as much slash as the entire rest of the year when I was doing it by hand cart.  I may get fatter, but I'll also get more done.  After a few days of usage, the battery meter has gone down by 1/10th. 
      Until next time...

      MSU 700 Oil Burning
      By Chile
      2018 Massimo 700 MSU. The machine started burning oil all of a sudden. One day fine-- next morning burning oil. Looking for advice. Do I pull the engine to inspect the top end or can it be done with the engine in place? Pro? Cons?
      Any and all assistance is greatly appreciated in advance.

      Which is the best oil to use ?
      By Prepper
      I have been doing a little research on which engine oil is best for UTV engines.  There seems to be some disagreement over using a good quality regular engine oil, and the necessity of using "M2" (or wet clutch suitable) oil.  My understanding is the "wet clutch" suitable oil has less friction reduction properties (hence a more responsive clutch with less slippage).  While less friction reduction properties would seem to be better for the wet clutch... it would not be best for the internal engine parts like camshaft bearings and other moving parts where friction is detrimental and would lead to premature failure.  Some folks swear you need M2 oil, while others say they have been using regular motor oil for years and their clutch is just fine.  Could they both be right ???
      Any thoughts ?

      Oil change
      By Joe Breaux
      Decided to do an oil change on the Massimo ...drained oil, screen was very clean even tho oil wasn't.  Then went to remove old filter.. holy crap ..I tried every tool I have, could not budge it..Went to store and got one of the end cap type..fit nice and tight, put a 1/2 in drive ratchet on it..nope..not moving.  Put a 18 on breaker bar o. It. The inside of the removal tool broke off!!  Had to weld it back together. Put a pipe on the bar for more leverage.  Finally broke it loose..
      I have never seen a filter in my 55 yrs of working on engines so tight..And i was the one who put it on 2 yrs ago.  JUST HAND TIGHT!
