Ben... I have attached a picture of the ECM. It's a MT05, but I am confused if my MT05 is the correct one for my single piston engine, or the ECU for a single piston engine is a completely different part number. If the MT05 is NOT the correct part number for my engine... then this whole situation of crank but no start makes sense. From what I understand about the history of the machine, it quit, and in spite of throwing parts at it (including a new ECM), it never started again. As I understand it, it appeared the fuel pump stopped working so they replaced it with a new one. When that didn't cure the problem they eventually arrived at taking a look inside the fuse/relay box to see if any fuses or relays were broken. They damaged the box trying to get it open, and called it quits, and sold it to the guy I bought it off of. He ordered the relay/fuse box but sold it to me before the part arrived. He gave me the part after it arrived but of course that didn't cure the no start issue. When I got it the issue seemed to suggest a timing issue so I checked the valve lash clearances. It was then that I saw the lobe for the exhaust lobe was about half worn off. I figured that by the time I paid for a new cam, rockers, and valves, etc. I could just buy a complete head assembly for a few bucks more. I didn't think the cam was wore off enough to keep the engine from starting, but it was worn enough that it needed to be replaced, and now would be a good time rather than later. Regarding the question about prior techs swapping pins, I think there is less than a 1% chance of that having happened. I will call Motorcycle Doctor tomorrow morning and see what ECM I should have. I bought the head from them, and also a seat assembly so they have had some business from me recently. Thanks... -
I. Fabbed a new motor mount for. That purpose. You have to check clearance on the shifting lever. If u are unable to do that you will have to call the belt dealers online till u find one that will help you. They are cheaper anyway. -
Hisunpartscentral.com to look up part numbers. Then, search the part number and description on ebay. -
20 sec video. Hit play. Time bar slider moves. Any tap on the blank screen throws me into full screen. no audio, no video. Times out---done. UTube video. I see the white mark "flashing" at the 90 deg point (9 o'clock with 12 being the cast index in the head). Confirm the cam lobes are down (valves closed) when the white mark on cam gear is at the top (12 o'clock) position and piston is at the very top TDC. If you got that, you are timed mechanically. If that is correct, you have one of three things going on: 1. The flywheel buttons or tabs "missing or skip tab" is off relative to the flywheel center keyway....which is locked to the crankshaft. The TDC was confirmed with the Cu wire test touching the top of the piston. Inside, the 18 knuckle poles stator (3 Ph. gives 6 magnet pairs) are independent of tabs on the rim...charging only. 2. Wrong part # ECM (DElLPHI MT05).......The pin outs are all the same. Software maps and advance curves are what change per application.. OR 3. The MT05 is for a 90 deg V twin motor w/ dual coil outputs.......... example is the KAW and KOHLER engines used on high end Zero-Turn mowers. The MT05 has 2 coil output pins: COIL A is pin J1-10 w/ J1 is Grey and COIL B is Pin J2-01 w/ J2 is Black Prior techs swap the pins???? eBAY Store of MOTORCYCLE DOCTOR. He carries HiSun parts and P/N. You have 2 parts to check out. Seen he has helped others on this forum. BEN -
Ben... pro tip on the video... when the video is playing, if you tap anywhere in the video screen options will appear. Tap on the Gear icon and you will see a list of options. Tap the playback speed option and select .25. It was easier for me to focus on the flash of the 180 degree flash in order to determine where the TDC flash was firing. It's obvious that it's several teeth off. However, I am certain I have the [single] line on the flywheel in the window when I set the cam dimple to align with the TDC casting mark on the head. So either the mark on the cam was placed incorrectly, or the flywheel mark was stamped I correctly. However, right as the video starts (you noticed the compression relief was not working) it seems evident that the cam/crank timing is correct because of the (I'll call it the "stall") of the movement indicates maximum compression. At that point the flash illuminates and the position of the cam aligns with the casting mark on the head. (I'll follow up more later)
