2018 Massimo 700 MSU. The machine started burning oil all of a sudden. One day fine-- next morning burning oil. Looking for advice. Do I pull the engine to inspect the top end or can it be done with the engine in place? Pro? Cons?
Any and all assistance is greatly appreciated in advance.

2018 Massimo MSU 700 EFI. I realize that this engine is essential the same as in all of the HISUN based Yamaha clones out there. I am in the process of performing a top end diagnosis/rebuild. I have an AMAZON top end rebuild kit on order in anticipation of this activity.
Question 1: When exploring the myriad of top end rebuild kits on the market for these units there are some cylinder assemblies that have "686 cm3" badging next to the cam cain tensioner boss. Others compatible with the unit do not have this badging. The existing cylinder assy does not have the 686 badging. I am assuming that this simply verifies that the cylinder assy is for a 686 cm3 engine which of course the stock 700 series HISUN engines are. Am I missing something here or is this just a manufacturer artifact? With or without the badging the application listings all indicate compatibility with the MSU 700 series engines.
Question 2: I have reviewed at minimum a dozen videos associated with this rebuild. To date I have not found one that deals with piston/cylinder clearance and/or ring gap verification. The advertised specifications for these various "top end rebuild kits" all indicate: Cylnider bore = 102mm and piston diameter=101.5mm. The math yields a .5mm (as in 1/2 mm) difference. That seems to be a very large piston/cylinder clearance. I realize I am referencing advertised specs rather than emperically measured values but the numbers have gotten my attention. I have referenced the FSM and found it to be somewhat confusing in this regard. Hopefully the experts on this forum can enlighten me as to where my observations are faulty here.
Any and all assistance is greatly appreciated .
Thank you all in advance,
Chile

I’m getting a 700-7 every startup. I’m having to change the plug every 100 miles on 93 octane gas. I got a lower numbered plug that is supposed to burn hotter. I’m wondering why that comes up every time I start it and if it’s related? I included a picture of the code or whatever it is. I haven’t seen the code in the owners manual or the hisun shop manual I have.

I just bought a new 2024 Hison 550 Stryker 2 months ago. this is the second time I have had this issue. It only has about 20 hours on it. The last time it happened we took it back to the dealer. it was a fuse. Since we live three-hour time driving there and back. I would like to find another solution if possible. I have tried all the fuses that seem to have anything to do with starting. Currently checking the battery. The battery is new. it came with the unit. It is probably 6 months old. the UTV has all power to everything electrical. lights turn signals and radio all work. When trying the key to start . it is 100% dead. as in it doesn't even click. There is a low whirring like the fuel pump is turning on though. The Unit was running and driving just fine. we shut it down for the night. The next morning my wife found it in this condition. Thanks for any Ideas or solutions??? Otherwise, it goes back to the dealer tomorrow. Just hope I didn't buy a lemon. Great little UTV when it does run.😅 anyone else ever have this Issue..?
