2021 T-Boss 410 — and yet another story from someone who bought one brand new without thinking twice about the fact there's no real service department like you'd find at an actual dealership.

The Problem:
Around 20mph, it bogs down like it's choking on something. Pedal to the floor, it sounds like it wants to go, but it just won’t. Makes no difference if it’s in 2WD or 4WD—same sluggish result. Reverse works fine. Shifts between 2WD, 4WD, and neutral without issue.

I’ve searched online but can’t find anything specific that matches what I’m (admittedly) guessing might be wrong. Truth is—I have no clue what the fk the actual issue is, and I don’t have the kind of mechanical memory others seem to when tearing these apart. That said, I’m good with my hands and can follow directions—I just don’t have any clear ones to follow right now. Any help or pointing to the right direction would be appreciated- next closest massimo service center was "fk you" miles away they said,

Mileage is at 1,568. As for the bogging issue, I tracked it down to the MAP sensor—a wire underneath had a clean break in a spot I couldn’t see. I got it patched up, and that fixed the problem. From what I read, the vehicle was going into "limp mode."

It’s been running fine for about a week, but now there’s a new issue…

After driving for a while—usually at a steady cruising speed—something starts clanking loudly from what feels like under the seat. It’s pretty intense and only happens after the vehicle's been going for a bit, so I’m guessing it’s heat-related. I have to stop and let it cool down before I can go again. Based on what I’ve read, it could be the clutch, but I’m not sure which part exactly

Condolences on your purchase of a Massimo non warrenty new utv ..from another foolish buyer who made the same mistake

Actually its been running fine for a long time now..after spending a ton of money fixing all the problms that plague Massimos   the biggest issue I had was once you drove it off the lot, Massimo and Hisun refused to warrenty anything.As you know mine broke in its first mile. And multiple times in first few months.They refused to fix it

Are you using good wet clutch oil? 

I have never even attempted to look at it let alone would I know how without instructions.

 

 

Just sending an update out into the world here- T-boss has been sitting out in the workshop and just now getting time to re-visit this thing. Read online this could potentially be shift lever or shift cable adjustment, possible that it may not properly be engaging at high speed or something? Anyone have thoughts on this?

      So I’d been shopping for an enclosure for my ‘21 TBoss pretty much since I bought it. Then they came out with half doors and that’s the only one that I could find. Then the other day I ran across one on Amazon for half the price of anything else I’d seen. The link is below and I’m pretty impressed by how well it fits. There is one Velcro strap on the top of the door that doesn’t line up well with the roll cage, but I’ll work around it.

      I have a 2007 Joyner 1100 sand viper and  before it even get's to where the thermostat opens up the oil pressure get's so low I have to shut it down. What could fix this ? I thought about adding an oil cooler with fan, thicker oil, or removing the thermostat. Any advice?

      I’ve never been around Coleman Utv machines. Do they have a good reputation, durable dependability. Could you compare them to yamaha rhinos or Polaris ranger
       
      thanks in advance

      I bought a 2017 Stampede 900 last fall that was new, old stock with less than 5 hours on it thinking that I would be getting a relatively trouble free UTV as compared to buying a used Polaris or CanAm, or Honda, etc. It's been a little quirky, but reliable. What I thought was just a minor issue with this model, the difficulty in shifting between R, N, L, H, etc., was just a characteristic of this model is now a big problem. I had to climb two very steep trails to get to the upper meadow of our hunting property, which seemed to stress the UTV more than usual since I was carrying some lumber to work on a platform for a hunting blind, and when I went to shift into park, I felt something give and it would not shift out of low, but it did move up into high gear.  I couldn't get it to shift at all at that point and the shifter felt mushy for lack of a better word. I was able to get it down to the lodge and when I investigated, I discovered that the straight, metal tube portion of the shift cable had bent to almost 90 degrees (see pics). I'm positive that it had already had some deformation that had happened previously and it had the right amount of resistance to bend to the point where it was unusable. 
      I have two questions:
      1. I suspect that there must be some other issues that makes this UTV difficult to shift, and I'm wondering if this is a common problem and if someone could enlighten me on what could cause this to be difficult to shift?
      2. Have any of you had this happen and if so, how difficult is it to replace the shifter cable?
      Any other advice is welcome, this is the first UTV that I've ever owned, so I don't know much about working on these or maintaining them. I'm relatively capable when it comes to working on my own vehicles in general, and I'm not afraid to take things apart and get my hands dirty.
      Thanks in advance for any insight, I'll be traveling most the day so I won't get a chance to look at replies until this evening.

      I have been searching and can't find much info on these units. Pretty surprising as every other thing I own I find a lot of info on. Researching for tech info and such it's like no one owns any of these yet I see them everywhere.
