From the 2014 and 2016 I've worked on it's a Siphon job. Mine are one piece Molded plastic tanks.

Thank you for sharing. Sounds like a simple but smart way to simplify a possible problem. I'll probably be putting a chain a couple machines. Again thank you for sharing. Robert

I have no real problem finding the marks on the Flywheel on any machine. The one I'm working on now has a new flywheel on it, made for High output Stator. It is a little tougher because that outer edge is very thin and so the mark is Small. but thank you for your input. They do fly by that Timing Hole quickly. I fine my more easily now that I'm using my Endoscope camera on my Cell phone. I just mount the camera, aiming at the hole and watch the Video on my phone. The hardest part here is getting that little camera mounted in place and stationery, have to get inventive at times. Again thank you for your time and input. Robert

Thank you for your input on physically establishing TDC as I had started working on that already. But I like your suggestion to use the Rim of the Drive Clutch by marking IT once you find the 3 points that you need. I've noticed references to the Firing Range in the manual when dealing with the Flywheel Markingbut have found no further info on what that is. I'll try creating my own TDC marks and Range of sorts. Ill also look for your post on your trick to keep the Chain in place if it's still available. Again, I thank you for sharing your ideas. Robert

Thank you for the reply and option to check. Unfortunately, I have 2 2016 MSU500s and 1 2014 Coleman 500 and None of them have such a marking but it was worth checking. I dug out my Endoscope hooked it up to my Cell phone and did a direct visual, 360 degrees and no mark. But then the manuals show reference points that don't exist. I'll probably try the Old physically locate TDC and go from there the best I can. A. Robertgain, thank you for your time and input

I have an issue and I'm hoping that someone can help with a little Wisdom. I have a 2016 Massimo MSU500 UTV that blew a time chain while out riding. It has been torn down to replave the chain and Sprocket amount other things that will be renewed. The problem comes in with setting Top Dead Center on the motor. The Manuals all teel one to line up hash marks on the flywheel with a point on the side cover under what's referred to in several place as a manhole cover. Its a large headed cap/bolt that unscrews and allows you to view the edge of the flywheel. There are hash marks on the flywheel that your supposed to turn the crank until you get the proper alignment between a certain hash mark and a reference point on the Case. Problem is there is NO reference point on the case there. I also have another 2016 MSU500 and a 2014 Coleman 500. Not one of these machines have a reference mark of any kind in that location. (I have pictures if needed) I know I can use the old pull the valve covers and rotate the crank and rely on getting the right point where Both Intake and Exhaust valves are closed at hopefully the correct point in the piston stroke. Is there any other reference point that could be used for this or is this the only thing left to use for finding TDC? Gotta Love documentation that doesn't match the equipment it's supposed to be for, any help would be greatly appreciated. Even if just to tell me that's about my only option. Thanks to all who even take the time to read my rambling question. Robert

Would this same fix apply to a 2014 Coleman SxS UT500? I'm just starting to work on one I just got and it seem to have some Shifting issues. I'm just curious. Thanks for your time and any info.

Thank you for responding and I think I am finding some answers to my question. I know that the TS301 is designed to Interface with the Delphi ECU and it's suppose to come with the Adapter for the Harness Cable connection, plus two other adapters for other Engines/Makes. I called Hisun Customer service and after a few minutes of being on hold the young lady there came back with the answer that I hope is right. She said that this unit is compatible with the 2015-Current year, the TS301 manufacturer updates the software that you can download from their site to keep it current. I stuck my neck out and ordered a TS301 and should have it by the middle of next week. Now my machine is one sick puppy but I will try this unit on my machine and see how that goes but if I have trouble I'll try it on my son 2016 MSU500 that's in good shape. I will report back whatever I learn and hopefully it will be Good news. Then the biggest drawback to some might be the $350.00 price tag, though for Test/Diagnostic equipment that didn't seem, Gulp, Overly pricey to me. Again thank you for your feedback and I'll post, in the near future, Robert

Hello All, I am trying to find a Scanner that is works for a 2016 MSU500. I found the Tiny Scan TS301 that looks like a decent Scanner but so far have not been able to get confirmation that this works on and older model. It has been stated that it works on the 2019 and newer but not sure about older models. It appears that the ECM/ECU/EFI modules are likely interchangeable between a 2016 and the newer 2019 and on but not sure of the Scanner. I am waiting for feedback from Hisun on this issue right now. If this unit is not usable for my model year has anyone found and a Diagnostic Scanner for the older machines, one that works and is Affordable? Thanks for reading my post and any information that you may have to share, Robert

The Fuse box has been located, it's right there under the hood.. My Bad.

Hello, I apologize for taking a while to get back to you, Fall projects have kept me away from my SxS project. I thank you for the heads up about the fuel, I had been made aware of this by another person. I got this as a basket case so the type of fuels not been an issue so far. I have tested and the injector power supply and that is ok but testing for any fuel output shows No fuel comes out as either a spray or stream. I have replaced the injector and the ECM module and not having any Diagnostic equipment beyond a Volt meter I am about to replace the O2 unit as this is listed as one of many possible failure points for the EFI system. I'll post if I start to make any gains in this project. Thanks again for your input on this, Robert

Hello Travis, Sorry I've been tied up and just got back to checking out my machine, following what you mentioned. I can't say that your idea alone lead to the answer but it got me in looking, Focused on just this task and not fitting it in among a bunch of other tasks. You got me in the right place and I took a closer look at a unit under the hood, near the battery box that someone before me had tagged as a CDI box. Why I read that tag and let it go at that I will Never understand, but I did just that. This time I looked at the Unit and notice the 4 screw holding a cover on the box, which cover the FUSES. Talk about feeling like a fool. Making myself try to focus on ONE issue at a time. Now I'll go back and Focus on my problem with the EFI system, No fuel to the engine. I Thank you for taking the time and responding to my posting because you did help me get this settled. Again thank you and have a good night, Robert

Hello All, I know this sounds strange but I've had most of this machine apart and putting back together again and I have NOT found the fuse box. Every Manual that I have access to says to Open the hood, take the top off the battery box and you'll find the fuse box. It's Not there in fact I Cant even find the three Connecters that would be used from the wiring harness. At least looking for what is listed as the correct Replacement part for this. Hoping that someone can make me feel Old and Feeble by coming up with some simple spot that I Swear I've already looked at but just did not see the Box. Thank you all for even looking at this and maybe getting a small Chuckle. Robert

Hello All, I got myself into a project with an MSU500 that I got after a dealership had done a teardown on part of the engine. The previous owner had been riding and it died. i was told the dealer said that whatever was wrong couldn't be fixed, parts not available. A bolt for the Starter Clutch had loosened and vibrated out destroying the Stator and shearing the Woodruff key. I have replaced all of that and put the motor back together. My problem now is I'm a Carb. guy never touched an EFI machine and I am getting no gas to the motor. I have confirmed that there is No gas getting to the cylinder, it fires with starting fluid. The fuel pump is working, i have pressure to the Injector and power to the Black and White lead on the Injector and the same on the Red and white lead to the ECM/ECU. I have been reading and trying to understand some of the troubleshooting steps that I've found. I also have done the test with the Injector pulled out and put in a container and tried, not even a drop of fuel comes out. I have also tried with a New Injector installed with the same results. I know this is not a Simple system but any input, or suggestions would be greatly appreciated. On a side note: This probably needs a new topic. but while I'm here and this will sound foolish but. Does anyone know where the Fuse Box is on a 2016 MSU500?? Believe me I've gone thru everything Under the hood. It is not in with or near the battery box as one manual says. Not one the firewall, inside out under the hood. I have spent hours working on both sides of the motor and Under it and I've not found it there. And after looking up a New Part for this I can't even find what are shown to be the correct Leads from the wiring harness to Plug into the unit. I thank you All in advance for any suggestions or info that you might be able and willing to provide, Robert

That's a good idea and I believe have a Tester, I'll dig it out. I didn't think about that, I did put a new coil and spark plug on it but beyond getting a spark never checked for it breaking down. Thank you Travis, I'll post how I do.
