Hello 

I have a 2022 Massimo t-boss 550. I’m looking for a fix for my timing problem. It keeps getting out of timing. Now I’m trying to find the proper parts for the linhai motor. I’m looking for tensioner chain and gear. If there’s anything else I can do to fix this issue please let me know. Unfortunately I can’t afford to get something better so I got to get it fixed. Thanks in advance.

If it's jumping timing likely the chain is stretched. Usually thats more a a function of wear on the pins from poor oil lubrication. Excessive metal in the oil, etc. It could just be poor metalurgy/manufacturing on the chain too.

The hisun equivalent uses the same chain as the Yamaha Rhino 660. They actually even accidentally use the Yamaha P/N in the service manual. There are a ton of these available sub $20 on amazon/ebay etc. Any chance that the motor uses the same chain? Can you send a pic and count the links? I'm assuming the motor may also be a Yamaha knockoff like Hisun.

Also you'll probably have more luck in the model specific forum.

Well what can I say somebody has to bye them! Lol

but again thanks for the advice , I’ve got it going and seems to be working pretty good so far. I added weights to the clutch and it seems to be a little better for what I use it for. By the way it was the chain that was finished that was the major problem. Although these Utv are made cheap and I had to learn the hard way.  Now that I know what not to do with it. The Massimo t-boss 550 might last me a little longer before I need to do more repairs to it! lol 

have yourself a great day and thanks again!

      Massimo MSU 700 Piston Clearance
      By Chile
      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

      2015 Massimo stalled and wont start. oil, new plug, getting gas verified. cranks but does not start
      By Tim n Deb
      Riding out today it acted like it ran out of gas,  stalled and died and would not start.   Towed back to house,  New  plug added this past month,  plenty of oil, getting plenty of gas, battery cranks good.   Trys to kick in and starts but doesnt.   Two days prior while sitting at a idle it died.  Added gas and it started did my ranch chores with it.  But just now it stalled out cranks but will not start.   Tried to find if fault codes came up on the clock like manual says but not sure I am doing that right.  Any and all help apprecated.  Thank you

      2019 Coleman 550 700-7 code at startup
      By amiracle40995
      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.

      Massimo T-Boss 560 or CFMoto Uforce 600
      By barticus73
      I am looking to buy a small UTV to do work around my property and priced a brand new Massimo T-Boss 560 through Lowes @ $10,500 out the door or a  Dealer provided CFMOTO Uforce 600 at $11,500 out the door.    Are there any glaring reasons to go with the Uforce 600 at an extra $1000?  Is one model more reliable than the other?  Any input greatly appreciated.
       
      Thank you,
