Head work question

Lenny (open to anyone who may have suggestions),

Without a doubt there is much room for improvement in our stock engine. If I decide to do cams I was thinking of taking the opportunity while having the top end apart to do some head work. I know you have ported & port matched your head. Did you do this yourself? I would most likely have a machine shop do mine. If I do drop it off to a machine shop what do you recommend I have done? I was thinking of porting, port matching & polishing. Is there anything else you'd suggest? I posted it here because I thought others may be having similar thoughts.

Thanks,

Paul

I did my own. Port matching is a must. You have to bring the gasket with you along with the exhaust pipes and intake tube assembly and the aluminum intake plentium. The plentium needs matching to the intake tube assembly too. When matching the head ports,you will see that there is a lot of room for cleaning up the pathways to the valves. Just pay attention so you don't cut thru to the water chamber. I used a piece of bent wire to keep monitoring the remaining thickness under where I was cutting. I didn't pollish mine as I don't feel it gives enough extra. If your a professional drag racer, maybe. Your basically trying to make the airflow as laminar as possible. You are not trying to get the ports as big as possible but shapped for a clean flowing curvature up to and around the valves. Do this after you match the ports. The exhaust manifold ports are a lot bigger then the heads exhaust ports. Try to eliminate the step in between the two. Even though the exhaust goes into a bigger area at the step, the step will cause eddies to develope which will disrupt clean exhaust outflow. It takes a whole day to do it if you stay with it.

Porting is a good idea but you dont need to remove head to replace camshafts.If you do want to remove head then port head and complete valve job.Which includes checking valves and

seats and guides plus replace valve seals.We can do this service for you we have done a lot of this type of work.You can do it your self if you feel like you can do it than go for it.

We carry all parts you need headgasket intake and exhast gasket and seals.

Thanks

Jose

      MY 400 is gutless. I would like to know if I can upgrade to a larger engine ?

      My 2018 Hisun sector crew engine cut off after about 15 minutes run. There is no indicator of what is wrong, no error code just die and won't restart until it cool down. I notice that the fan is not running but the temp indicator is on low temp, no overheat indicator. I checked the radiator fluid, it is cool to touch.
      Cooling fans are working, I can hear it running once awhile if I can get the engine warm up enough.  Thank you for all the help.

      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.

      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.
