Slow 2017 HiSun Strike 250

2 posts in this topic

Guys,

I need some expert help..  I just bought a 2017 HiSUN Strike 250 and was real disappointed to find out that there is an electronic spark cut out at 30 mph.  Every article that I read prior to purchase said that the unit could hit 45-50 mph with the pedal stop screw removed.  Not the case with my machine.  Never bothered to ask the dealer before purchase, so it is my fault...  My guess is that HiSun got some flack about thier "kids" machine doing 50 mph and were forced to add the electronic limiter..  Can anyone verify that previous to the 2017 model that the machine can actually could do 45-50mph with the just pedal screw removed?  If so, what RPM is it at when doing 45-50 mph.  Maybe I can get an older version of the Delphi ECU, assuming that is where the spark cut out is located...?

The machine is definitly full featured, but as you all mention, needs to be gone over after purchase.  A-men to stipped screws, and if you suffer from a crazy squeak sound that sounds like chains dragging, check the torque on the suspension a-arms and shocks.  Ours were so tight, we could barley get them loose and the suspension would not move, essentially zero travel.  Once we lightened up the torque, greased the plastic bushings, and added blue threadlocker, the suspension actually worked and all the squeaks went away.  Also have same problem with the shift linkage rubbing on pipe and also pipe rubbing on chassis.. This weeks project!

Any help on the speed would be awesome!

Hello there, there are a couple of things to address here. First off is to make sure when the throttle peddle pressed all the way down, that the throttle is also opening all the way. You can check this by removing the center cover. When you press down on the throttle, reach over to the butterfly valve and see if you can open the throttle any more on the throttle body. If so, adjust the throttle cable. But you need to make sure when the throttle is released that the throttle also closes as well. Meaning you will have just a little bit of slack in the throttle cable. You don't want the throttle body hanging up causing the engine to rev. After that, there is come control in the ECU, but there is also a electronic speed limiter, located under the dash by the winch control box. Try to make sure the throttle is adjusted properly first and let me know. Matt
