I'm watching a snowmobiling show, SnowRax, on the outdoor channel. The Polaris Supertrax snowmobile is pumping out 150 horses from a 800cc Liberty engine. Our horsepower output is ridiculous in today's market. Someone needs to upgrade / improve our power-plant or replace some Design Engineers. JMHO!

Your right but our engine is basically designed for fuel economy and long life with emmision control for the automobile market where as the snowmobile engine is built as a race engine right to start. Our engine I beleive is a near clone to the engines they use to use in ralley cars overseas and they get a lot of horespower out of them. If the crank and rods and pistons were changed to preformance stuff along with other stuff like superchargers, I think our engines could turn out 200hp. But, were going to try it with your engine first I don't want to blow mine up. I even cut my rev limit down to 5700 RPMs just to stay conservative. I don't miss the revs nor need them.

Sadly it is not just the engine. IF we pulled 200hp our of our engine the rest of the drivetrain would be trash very quickly. Just venting! Even my race car has to run a car Toyota diff mated to the 1250cc Yamaha motorcycle engine to with-stand the power. Plus our parts are not CHEAP! You can purchase a used BMW diff for $250 but can't touch a Joyner diff for that! Still venting! My last set of Brake pads cost $6 / corner and now they are $15 / corner. Things aren't getting better! Still venting.

Have you seen the maintenance schedule for some of those things your venting about and thier horsepower? My bosses husky super motard your supposed to replace the cyl piston and rod after every 10 hours or less. Crank at 20 hours. This is "extreme" use. I would not vent too hard about the pricing. As parts become more readily available in the near future you will start to see some of the pricing drop. Enjoy your buggy for what it is. If you wanted fast and lots of power then maybe you should have bought something else? You say you want low end power, that snowmobile doesn't make any power below 7000 rpm. Your comparing apples and oranges. I like my joyners and will stick with them. You could get a all new crew in and redesign everything but then what? You buggy turns into a 17k buggy. Who wants that? I feel you on this but then again what are you really expecting? Go hop on the waiting list for the new rzr and let us know how it performs.

My CRF450R owner's manual says you need to do a top end rebuild at 65 hours. Have had it for 7 years with 400-500 hours. Have never had to change a thing other than oil & filter and it has a ton of low end. Thanks for a light at the end of the tunnel on parts. High prices does bring alternativea into the market which is a good thing. At the time WE WERE the go to power but CanAM & RZR have raised the bar. Hope your & Silverbullet's aftermarket efforts are fruitful or we WILL be left behind as a product and in a drag race. More power doesn't mean we have to give up low-end, waiting for your fixes.

      I have a 2017 Intimidator XD4 800cc 4x4.  It will run great and then it's like it goes into safe mode and only runs on 1 cylinder.  It's not fouling out the plug when it happens.  Some times when I stop and restart it, it works fine.  First I thought it was a spark issue, then a fuel issue, but I feel like it's a short in the wiring some place.

      I swapped out the Subaru motor for a Predator 670cc. If I remove the heat shield around the muffler, The stock muffler sits in there just fine with 1" to spare.
      Only problem is the exhaust exit is toward the back seat instead of out the back.
      Do you all think that the stock exhaust would be okay (just as effective) if cut a hole and welded a pipe on the reversed (opposite) end? Of course, plug the old exit end. Other option I thought of was to roll a tube 180° with a 7" center line radius and finish extention of 12" or so.
      Any thoughts?

      Can anyone tell me how to get the engine codes to display on a 2012 Bennche Bighorn 700X?  I played with the gauges once and lucked up on this but can't remember what I did.  Will the codes automatically display if there is a code or do you have to cycle through the display?

      This post will explain how to hook up your PC to the ECU of a Hisun/Coleman/Etc UTV to be able to read error codes & engine parameters for troubleshooting purposes.
      This is applicable to all small engines using the Delphi MT-05 ECU. This should cover all fuel injected Hisun models, as well as various other Chinese FI engines, as the Delphi MT-05 ECU seems to be the favored ECU solution.
      Even though we get actual engine error codes to display on the dash, sometimes we have “pending codes” (not yet confirmed by the ECU) or other intermittent issues that are hard to diagnose, for example a poorly connected sensor that may give intermittent false readings, or a sensor that’s putting out bad date, but not bad enough for the ECU to realize.
      The setup requires 2 cables, which are available for around $25 combined, a PC with a USB port, and some charityware software called “HUD ECU Hacker”. This gives the same functionality as the $300 dealer code scanner for a fraction of the price.
      In searching I found info about HUD ECU Hacker, but I have yet to see info anywhere about how to hook it up to a Hisun, so I took the leap and bought some cables, and made it work. I will show a step by step of how to do so in post two.
      I will be breaking this down into 2 posts:
      Delphi ECU Info & Overview (This post) System setup & use Delphi ECU Info (Skip ahead to the next post if your eyes glaze over technical details)
      The Delphi MT-05 ECU was developed to allow small engines to use fuel injection. A fuel injection system requires feedback from various sensors to operate efficiently. This feedback allows the adjustment of ignition timing, fuel injection volume, etc to efficiently and cleanly produce the most power possible from a given engine.
      The MT-05 ECU has a number of sensors that are required for proper functioning including; Coolant temp, crankshaft position, intake temp, intake pressure, exhaust O2, throttle position, as well as some other optional sensors that are used on more complex vehicles.
      From the sensors the ECU adjusts: Fuel injector timing/pulse, Idle air control valve, and ignition coil

      The Delphi MT-05 puts out diagnostic data, however it is not ODB2 like a modern car, where is where it gets tricky reading it. There are three options, there is an old 16 bit piece of software Delphi has that is not able to run on a modern computer, there is the motorscanner tool for dealers ($300), or there is freeware HUD ECU Hacker with the proper cables.
