I have a yanmar longhorn 6 seater which I believe is having fuel delivery issues.  It will run off of starter fluid and will sometimes run on gas but will not idle.  Fuel pump is new and verified to put out 56 psi.  Injector is new, I'm reading 10.5 volts at the injector, gas is new.  The unit will run when the engine symbol is not present at the gauges.  Diagnostic port doesn't appear to be present, can't find it where yanmar says it should be.  Oil is full but old.  Any ideas what's going on here?  Is there a maintenance function that will shut this machine down if it has old oil?

I know the Axis/Hisun manual says it has a low oil switch that will shut down that machine if it has low oil.

And a pull start generator gave me a fit one cold day when electricity was off due to a storm. Because the oil change I did a month before. The oil was too thick when cold.

      New owner with questions
      By Poppateets
      I just purchased a used 2023 Massimo warrior UTV SxS 1000mx with 600 miles on it. I didn't even get a full day of riding and the driver's side rear axle broke. I'm pretty sure it was already going bad because we would hear a noise once in a while. I'm wondering if anyone else has had problems with theirs. Also looking for places to buy accessories.

      bd 300 bulldog shifting issues
      By Dennis
      I have  a bulldog i bought from home depot in 2013.  In the last season it started refusing to shift from neutral to either forward or reverse.  I changed the trans axle fluid and made sure the cables were lubricated and free.  With a lot of coaxing, I can sometimes get it to shift.  once I start driving it, things improve until I let it set awhile.   Any suggestion on where to go from here?

      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...
