Initial Start Up Procedure


Travis

Recommended Posts

Im about 3-4 more weeks on my engine. (Im counting one week to re install into frame since thats how long it took me to take it out) What should i do when i first start it up? I know not go over 3/4 throttle.

Any other tips or tricks?

Kawasaki single cylinder 286 cc. The usable compression range is like 114 psi to 168 psi, i believe. What should i shoot for?

Other than just to take it easy, there's not much you can do. Everything is dependent on how well it was assembled. Don't get it too hot, don't over rev, don't run it too long. Just short easy trips, till you're sure everything is fixed, and running normal. Check for leaks, if everything looks good, then I wouldn't get above half throttle for awhile. Of course that's a lot of weight for a small motor to carry. So maybe three fourths throttle, but no more for at least fifty miles. Although full throttle won't usually hurt one of these, since it's probably got a rev limiter, it's never going to be good for it. No heavy loads in the bed, or pulling a trailer, for the first few trips. I'm assuming it has a speed limiter, and/or a governor on it. If that's the case, you should be good on the break in after a couple dozen trips around the farm. Except for high rpm revs, which are never good. The rest such as driving on the street, should be okay. I think street driving at slow, to medium speeds would actually speed up the break in.

   The compression isn't adjustable, so just be happy if it's in acceptable range. With new rings and such, I'd expect it to be up there, but certainly not at, maximum.

      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.

      2020 Massimo Buck 400 - Won't start. Can hear the starter spinning, but motor never turns. Relay? Starter? Worked fine one day and not the next. Thanks for any help you can provide.

      I installed a new GY6 150cc engine in a Bull Dog Pup 200 and when I put it in drive, it grinds for a second and then runs fine.  Works great when i place it in reverse.  Could it be from it idling too high?   Any help would be greatly appreciated.
      Thanks!!!!

      I've had a battery failure and need one replacement.  The local distributor told me it might take up to four weeks to get one.  I'd like to order one in sooner than that if possible.  Any help would be appreciated.

      Hello everybody. I just tore a Yamaha apex snowmobile apart and I’m about ready to start fabbing up the mounting system for this thing. The Yamaha was in a stand alone setup. The gearbox was hard mounted to the chassis with the engine on four rubber mounts and that’s the way I’d like to build this too. 
      I ordered the secondary clutch from STM but it hasn’t arrived yet. The Yamaha secondary slid about 1/4” axially and I’m assuming that was to tolerate the fluctuation from the engine moving in the rubber mounts because of torque. I don’t believe the stm clutch has that slide action. 
      So my question is if I was to hard mount the rzr gearbox and leave the apex engine in its original mounts would the fluctuation from the primary under torque be bad enough to make the belts too far out of alignment ? 
      I’m not a fan of hard mounting the two together like Polaris does due to no ability to adjust the clutch alignment and the apex is sitting with fresh mounts installed in my garage as it sits. If I went with the rubber mounts that it already has I could be fabricating tomorrow. I’ve seen the kits available and I’m not paying that kind of money. Everything I need to fabricate this is sitting in my garage already. 
       
      Oh and the speed sensor. Anybody have to mess with this yet ? I have to assume the ratio from the apex gearbox and the Polaris gearbox are different. There’s no way I’d be that lucky
