MSU 700 Compression Specs


Recommended Posts

Does anyone have the compression specs for the MSU 700 engine?  Mine is smoking something terrible at times and I would like to do a compression test prior to tearing it down. 

Also will too much oil cause it to smoke?  To improve the wet shoe clutch wear, a dealer/parts supplier suggested that I raise the oil level to the bottom on the dip stick threads, which is approximately 3/4 of a quart.

A little background this is a 2016 (I purchased it new in April of 2016) MSU 700 (Tractor Supply version) it now has approximately 500 hrs and 2900 miles on it.  I use it almost daily on the farm and also take it to the VA and VW mountains to trail ride.  I thought the belt was slipping, well I know it was slipping, so I replaced the belt and changed the oil, but new tires on it, greased, etc... When I finished it smoked like a freight train and I realized that the clutch was slipping also.  Oh, I've used Mobile 1 V-Twin Motorcycle (supposed to be for wet clutches but not MA or MA-2 approved) oil in it since the first oil change.   I replaced the wet clutch and switched to a synthetic motorcycle oil that is MA-2 approved.  No more belt or clutch slipping but it still smoked heavily.  Yesterday I ran it at the Rev limit in low and it stopped smoking.  I checked the oil, added a little to bring the level back up to the dip stick threads.  It started smoking again until I ran it at the Rev Limit for a few minutes then it stopped smoking.

It wasn't smoking, at least noticeably, until I changed the oil and re-filled it to the level recommended by the Dealer/Parts Supplier.   I will say that the oil level was low when I changed it and I had raised the oil level after prior oil changes as well.    But when the clutch failed and he reiterated that the type of oil and oil level were very important to longevity of the wet clutch, I may have added too much oil.

I drove it last night and it smoked very little.

Put in the manufacturer specified amount. The guys that built it know how much it should take. 

As to the smoking. If it's rings, it'll have a blueish tint. And it might smell a bit like unburned gas. Set the proper oil amount by the volume suggested by the manufacturer. Not the dipstick. Nor the guy at the dealer. Then run it awhile, and see if anything improves.

      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,

      So i have a 2011 EFI 700. the SxS will crank right up everytime without any issues. If i let it run or ride it for about 10 mins it will shut off and then it may turn on if i am lucky but most time i have to let it sit for like 3 hours and then it will run again. i have done the following
      -New fuel filter
      -New injector
      -New spark plug
      -New coil pack and plug wire
      -New air filter
      Also could i get a grizzly 660 engine and put in it or would it not work.
