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.

      Hisun will not change gears while running
      By Buck
      My father-in-law has a Hisun 750.  It has started to not change gears while running.  He can turn it off, change gears, then restart and it will change.  I thought it might have something to do with the brake but can’t find any info.  Thanks in advance for any info.

      2018 Massimo 700 MSU Maximum RPM
      By Chile
      I have a 2018 Massimo 700 MSU with the Delphi MT05 ECU.
      I have seen an alternative ECU reset procedure that involves running the engine at WOT for 5 seconds in neutral and then shutting down while throttle still at WOT.  The articles include comments that the rev limiter will prevent engine overspeed ad attendant damage. 
      1. Is this actually a recommended procedure for restting the ECU on a 700 MSU?
      2. What is the rev limited maximum RPM for the 700 MSU?
      I initiated this procedure but when the RPM exceeded 6000 I immediately terminated the process. It simply seemed excessive to me to continue.
       
      Any and all responses are greatly appreciated.
