I have a 2015 Massimo 500 that idles really high and it will not let me shift into gear while it's idling. Not sure where to start. Also it will bog down and stall constantly. Starts right back up everytime. Advice please.

I don't know a whole lot about these Massimo brand, but it could be 2 things, a vacuum leak, causing excess air to enter the combustion chamber, or it could even be a electronic issue.

The bogging makes me think it's more of a vacuum leak, how I find vacuum leaks is I get a bottle of WD 40 in a trigger Pack, not a aresol can. And with it running spray around the injectors and lines and if I spray it in a certain spot and the engine speed changes, that's where it's leaking.

      Massimo durability and parts
      By Smittay
      (posted a similar question to the Hisun folks) Looked at a lot of UTVs lately. Couple Questions about Massimo. Some people say they are just cheap with no customer service. Other people seem to have no problems with them.
      Any opinions on Massimo durability?
      Heard parts might hard to get. Is that true?
      What models are the best?
      If you had one and didn't like it what do you recommend?

      American Landmaster TW450 Won't Start!!
      By malenurse13
      We just bought a used 2017 American Landmaster TW450. No hour meter that I can find, so not sure exactly how much it has been used. 
      The first 2 days we had it, the starter was a little sketchy, but it started after 2-3 tries. Sometimes when turning the key, we would hear a loud metal "clink" sound. Like the starter made contact, but didn't have enough power to turn. 
      THIS MORNING... Turning the key, we hear a single click sound. That's it. Even with a new battery, the starter is still doing the same thing. Both batteries (old and new) were reading 12.8 volts on volt meter. So I'm wondering what else could be going on? Any ideas on what to look for would be greatly appreciated...
      Thank you!

      2013 UT 500 won't go into reverse.
      By lonerider98
      At the end of last year my Coleman UT 500 will not go into reverse. I can hold it over toward the reverse to move it nut it won't lock into reverse. Anyone have this problem? Winter is just about over and going to have to get this resolved. Thank You!
