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!
Buying from Silver bullet like sushi at a truck stop? Over the years seeing him on this forum I assumed he was legit but now I am seeing lots of negative feedback. Selling engines you don’t have and taking money on a website for false inventory is fraud. Not sure if that is the case or not but getting sinking feeling it might be the case after making an order yesterday and getting no follow up or response immediately to my calls for clarification. Anybody with experience?
I bought a new HISUN HS400 EFI recently. Still in break-in period with about 15 miles on it. This thing starts and runs just fine, like new, but at about 12mph it sputters/stumbles/boggs and does not want to go any faster than 12MPH.
Does not sputter in neutral and revs very well in Neutral.
Any thoughts on what is wrong?
