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.

I've been looking at various types of UTVs in the 400-700cc range. It seems that Massimo has a really good price point but I don't know much about their reliability and availability of parts. Been looking specifically at their T-Boss 550. I've heard the parts might be an issue because the network is smaller, but couldn't find much info from owners.

Here are a few specific questions about them

1. In your opinion, are the reliable? Specifically, have you hand any parts break that in your mind shouldn't have? 

2. If you had one and got rid of it, what was the reason? 

3. If you don't recommend Massimo, what would you recommend (even if it costs a little more)?

4. How easy is it to find a place to service them? How easy is it to get parts if you want to service it yourself? 

If you have any other advice, I would appreciate it. I'm also looking at the Hisun Sector 550.

Hello 

i have a 2022 Massimo t-boss 550. And it suck’s! I’ve blown 3 clutches 1 was my fault. The starter bearing (clutch). And now I’m dealing with timing and valves. Once you get the bugs out and know what it can’t do it’s ok! And no service. The one person that did help me at Massimo Canada got fired. Lol I’ve been fixing mine since I have no money to buy anything else, by the time I’m done with it it should be ok. I hope lol

good luck!!

2016, Hisun 500 turns over great but Spark plug is firing when I turn the ignition key on. I’ve got good fuel pressure to the injector. Pulled plug out and it is wet with. gasoline. Air filter is clean. Turns over great just does not even try to pop or start.. I’ve checked off uses and they are good when I turn the key on I’m getting power to the injector.. I’m not hearing the injector pulsing, but may just be my hearing.. With the spark plug getting wet with gas I feel like the injector is pulsing and spraying. Any suggestions would be great. I don’t know the hours on the unit offhand, but it has 600 miles on it. Thank you for your comments and advanced.

Hey Buddy 

I would start with checking the valves and timing. 
good luck and let me know.

I checked the parts diagram for my T-boss, and the parts are the same, just numbered differently. Assuming that the starter meshes with the idler gear, which meshes with the crank gear, you should only be able to spin the idler gear one way.

If I am correct in my assumption, your starter clutch (#2) is bad. I don't know the level of difficulty in replacing the starter clutch, so I can't help you there.

I believe that you are correct. And the starter is not hard but for the gearbox it might be different. But with some mechanical knowledge and this forum I’m confident that it shouldn’t be too bad. I suggest that you take pictures before you start taking it apart it helps. Lol 

good luck and let me know how it goes

Hey Dave 

I had that issue with mine, I brought it in for warranty and it was a one way bearing on the starter drive. That’s what they told me. Hope it helps. 

Hey Dave 

when they fixed mine they only changed the bearing or clutch. 
something else to watch for with these bikes is the timing. The tensioner seems to not work properly. I don’t have a permanent fix yet, but the I’ve got it down to about 1hr to do it now and I keep all the tools in the bike just in case it happens in the bush.

2020 Massimo Buck 400 - Won't start. Can hear the starter spinning, but motor never turns. Relay? Starter? Worked fine one day and not the next. Thanks for any help you can provide.

Thanks 

It was one of the first things I did. But I will take any other suggestions. 
But I did learn that I should be putting better gas not just regular. 
thanks 

Hey 

I’m having issues with my 2022 Massimo 550 it will not start. It was all good I was driving it all morning then I go to use after lunch and it started ran for about 100’ then just died. I’ve checked plug, fuel, and that’s good now if I my foot on the gas it will sputter. I removed the injector and it was dirty I cleaned it didn’t help. But if I hold the injector about 1/4 “ above the hole the bike starts. Any ideas or suggestions ? I’m 6 hours away from the Dealership so trying to avoid the drive. 
thanks
