  2. Digital Dan, Thanks for the reach out! Yeah, did the same thing and am now able to get 8900 out of the machine per the gauge on the dash. Definitely better, but like you say, you still bang up against the cutout at 8900 rpm, which is still only about giving me 36 mph on the speedo. Much better than where we were, but still will be annoying on the roads, especially heading downhill. It now seems that we are not loading the engine enough to keep it from banging up against the max rev limiter. The obvious next step is to change the final gearing from 42 tooth final sprocket to a 40 too
  3. Awesome, for sure I will mention you!! Also, can you explain what the Speed limiter 37910-120-0000 under the dash does? I believe this is what you referred to in past comments? What does it do and why would they have both a separate limiter and the rev limiter in the engine?
  4. Let's say money wasn't an issue, do you know where I could get a new 2015 ECU?
  5. Thanks so much!! Do you think I can still get them? If so, do you know who can sell them to me?
  6. Awesome info!!! So assuming we can get the ECU rpm limit changed, via reprogramming or a getting an 2015 unit, then all we have to do is compensate for the gearing changes. So it's unlikely that those of us with slow units will make the internal engine changes, but we should be able to compensate for the reduction on the final sprockets, right? Are you confident that just changing the rear sprocket to 38 will help, or will we have to go much lower in tooth count? Also, what does a stock 2015 unit max out on in respect to revs?
  7. When you say "gearing inside the engine" what does that mean? In the 2 speed geared transmission, in the CVT, or the final sprocket ratio? This is great information, please share more insight if possible. Thanks!!
  8. Hey thanks again everyone for helping me with my original question.. Bear with me, but I am still confused as to how all of us that bought 2017 or newer units can get back to the prior models performance where the top speed was much faster. (up to 50 mph per magazines reviews) . If any Advanced Members can make it really clear what Hisun exactly did to slow the machine down, then the the rest of us with 2017 machines have a chance at getting the top speed back. I have been told that the EFI module (Delphi MT05) has been reprogrammed and a spark cutoff has been added at 7000 rpm.
  9. My first impression are that the quality is good, not great. I have had the machine up on two ATV trips to Northern Wisconsin and honestly had to go over the machine to get things right. The squeaks and rattles drove me nuts and required me to tear parts of the machine apart to figure them out. If you are not very handy, go with the Polaris unit. I ended up not leaving the machine at camp and decide to bring it back home to do more work on it to get everything right. My dealer is no help, so I have to do the work myself. If you do get one, these forums will help you get the ma
  10. The HiSun Strike 250 is really a kids machine, not ideal for an adult. I just bought a 2017 for the kids and I am 5'11" and weigh 175 and I barely fit into the machine. The new machines are also speed limited to 30mph, so it could get rather boring quickly. I would not recommend it. Polaris RZR 570 would be my recommendation, a bit wider, but great entry level UTV for adults.
  11. 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 actual
