I'm using an outdoor bluetooth speaker mounted overhead on the cross member. The internal battery lasts about 2 hours at high volume, but I can also power it from the UTV if I want to run a wire. I was planning to wire it into the electrical, but haven't really needed to yet. Everything I listen to is on my phone... music, podcasts, etc; and I already happened to have the speaker. It was a quick and easy way to get a sound system going, and it has worked well for about 5 years now.

Send me one for my Hisun Sector 250 and I'll test and review it for you.

Hydrogen combustion and Hydrogen Fuel Cells are the only "green" solutions that makes sense. Too bad finding fueling stations still isn't anywhere close to where we need to be.

I'm amused by the fact that my "little" 2016 Sector 250 tops out at about 43mph with my 250 lb butt driving it and is quicker than my brother-in-law's new Axis 550 (with 200 lbs driver); which tops out at about 37mph. I easily win the "run and get the mail" and "take out the garbage" races; but the 550 4x4 is a beast in the woods and off trail (which is why it gets to go to deer camp, and the 250 stays at home). My Sector 250 isn't stock, btw. I replaced the ECU with an older, higher revving ECU that HiSun USA pulled out of all the "too fast" first year 2015 models and changed the rear sprocket (2 teeth smaller... 42 to 40 I think, if I remember correctly).

It's a few MPH faster, but not very much. I think maybe 2 or 3 MPH. The change in peak RPM is very noticable though. Mine went from about 7800/8000 max to 9000 max.

I'm curious about the same thing. I haven't changed my rear sprocket yet.

Are you absolutely positive that the tank is full? I thought I was having the same problem with my 250 Sector when I first got it, until I filled it up to the point where gas was just about to start over flowing. Then the gauge showed full.

Fun Dad, I bought an ECU for my 250 off eBay with the intention of sending it to Matt for reprogramming, but it came with original firmware on it. My buggy nows revs up to around 9000 RPM before electronic rev limit starts stuttering. My top speed has increased, but I'm not sure how much yet. I haven't let it "stretched it's legs" completely out yet. Here's the link: https://www.ebay.com/itm/ECU-Controller-UTV-250-ECM-HS-EFI-Box-39200-120-0000-HiSUN-MASSIMO-BENNCHE-TSC/351694181290

Hey Matt, I received my hitch today and installed it. Very nice job with the design, and I'm very impressed with the quality. Thank you!

I used to work on snowmobiles a lot (before moving south) and their exhaust pipes are held together with the same type of exhaust springs. I have a couple different "spring removal / installation" tools, but none of them are quite like that. You might want to patent that bad boy!

I believe this is the muffler that Orebonder used... http://www.walkerexhaust.com/catalog/walker-exhaust-systems/e-catalog-lookup/22229

I think this may be the service manual for your machine http://www.atv4usa.com/catalogs/HS500-700 UTV Service Manual.pdf

What's the turn-around time for getting the ECU re-flashed? Can you re-flash it the same day you get it, and send it back out that day or the next?
