I was wondering if it is normal for the RPM to go up and down while keeping constant pressure on the accelerator.I noticed today while sitting in neutral i reved it up to 1500 and tried to keep it there.It would go up to about 1700 and drop to 1200 and back up and down,would never stay consistant.I went up to 2500 and then it would jump to 2900 then drop to 2200 and back up to 2900 and down again.I made sure I was not doing it with the pressure from my foot.I was wondering if this was normal.

Thanks in advance.

My opinion is yes, I have a lever to hold the throttle, because of my leg disabilities, and it doesn't hold a constant RPM either, never worried about enough to figure out why, yet. I am building a cruise control for mine so I can set it at 2500 or so and let the controller hold the throttle relatively constant went going up a rough hill, usually I end up full throttle because I can work my feet very well. The problem with the lever is that as I go uphill, I need more, and as I go down hill I need less.

it just seems it should be holding a consistant rpm.I thought at first it might be fuel regulater not set correctly but it is at 55psi.

      2020 Axis 500 - only getting reverse and neutral
      By JimG
      Recently, my unit Axis 500 (2020) will only go into reverse and neutral. I am not able to get high or low. The engine itself sounds fine and I do not have other issues on this unit. I change the engine oil but have not yet changed the gear oil.
      Before this happened I occasionally encountered issue where going from reverse to high gear, it would grind some and i had to reposition to shift into high gear. I also for last couple weeks heard a squeaking sound. I couldn't tell what it was. Was looking for a grease point I missed.
      The unit has around 70 hours and is kept in the garage.
      Anyone else encounter this type of scenario? Any suggestions on troubleshooting would be appreciated. Thanks.

      My Odes Dominator 800 bogs down when it gets to 25mph
      By Bjabbarw
      My 2021 Odes Dominator 800 bogs down at 25mph and won’t go over that speed. I have changed the fuel pump and it still does the same, it runs and idles fine, it has great reverse speed, but it won’t accelerate past 25mph. Any Ideas?
