Hey everyone. This is my first post and I hope you all can help out here. I have a 2016 Massimo 500. I'll start out with "it is a beast" I have worked the crap out of this thing and it keeps on coming back for more. Never had an issue except one battery replacement and this cold starting thing.  When I start it up, summer or winter, it requires being in neutral, pre-loadiung the fuel by pumping the gas pedal (like an older carb model) and then once it starts, I have to maintain 3000 RPMs or more for at least three or four minutes before it will idle on it's own.  After that, it will idle for as long as you ask it to.  Any input?

      2021 Axis 500 4 month Review
      By mac66
      I bought a used 2021 Axis 500 last April.  Low mileage and got it for considerably less than what they go for new.
      The first thing I did was change the oil/fluids and also put a new drive belt on it.  The only other thing I did to it was add a rear vinyl window that zips open and rolls up to keep the weather off.
      I used it on my 52 acre property to check trail cameras, service the food plots, haul fertilizer, seed etc etc. It's has a good size bed and is not too big or small.  It has worked well as a utility vehicle. 
      Other than using on the trails working around the property I haven't used it much off road...at least until last weekend when I went on 74 mile group ride around the county. In my state it's legal to ride on any road that's not a state or federal highway. The group started in town, rode about 30 miles on back roads to the state ORV trail system. Then did about 20 miles on the trails and then headed back via back roads to town.   
      It had rained for 2 days straight prior, so the trails were one mud hole after another.  It was very challenging.
      The good...
      -It worked fine, never had any kind of issue with it since I bought it.
      -It kept up with more expensive machines on the trails. I was the only one with a CCC (Cheap Chinese Crap) machine.
      -Fairly comfortable to drive.
      -The roof, windshield and rear window kept most of the rain off when it started raining in the afternoon.
      -Okay, I cheated. I peeled off the AXIS 500 stickers on each side. Everybody in the group assumed I had a Rhino. They didn't ask, I didn't tell.
      The not so good...
      -The horsepower rating on the 500-cc engine is 24 hp but it seemed underpowered. While I could go about 35 mph with the pedal to the metal on pavement and hard packed dirt roads the best I could do on loose packed roads was 27 mph. I had trouble keeping up with the others in the group.  It also bogs down on inclines in high gear.  On the other hand, in low gear and 4wd I didn't have any problems going through mud or sand or up hills.
      -It is LOUD! Had to wear shooting earmuffs to keep my ears from ringing while riding. Going to have to address that.
      Overall Impression...
      I was impressed with it on the trails, and it is a good utility vehicle for working around the property. Considering what I paid for it I am very happy with its performance.

      Bit of background. First the machine would take for ever to start. So I adjusted the valve shims into spec and made sure the timing is correct. Starts perfectly now. 
       
      now it fluctuates on idle. Bogs down, Revs up, repeat. I noticed the fuel pressure drops from 60psi to 20psi while that happens. It also bogs down at the lower end of each gear, higher rpm seems to be fine. Seems to struggle under load. In neutral it revs up perfectly. 
       
      brand new fuel pump, fuel filter, gas. I noticed on the fuel pressure regulator there’s that vacuum nipple, it’s not attached to anything and I’m not sure where it would go. Possibly the problem? 
       
      Another issue is the tip off the end of the exhaust is broken off, sensor is still attached and connected. Could that cause these issues? 
       
      my next plan was to look into the pressure regulator and voltage to fuel pump while driving. Is there anything I’m missing or any ideas you guys have? 
       
      thanks!

      I have a Coleman Outfitter 550 purchased in January 2022 that runs and operates pretty well.  65 hours on it so far.   It is a work vehicle for my 10 hilly acres with two 1 acre woods and 5 acres of "lawn".  The rest is under a lake. 
      My parking brake does not seem to have any grip.  It worked when new but after a month or so, it is just almost useless.     I press the parking brake pedal hard until it stops. Still, it won't hold even on slight inclines.   I don't see the caliper move as I press the brake pedal down.  There seems to be plenty of pad left on it and the rotor is shiny as if it is rubbing a little when applied, but not enough to stop it from rolling. 
      Any thoughts on possible causes?

      Please help 2021 Axis 750 crew won't shift into gear and found milky oil on inspection
      By BMurph
      Hello everyone! I am new here and have no experience with UTVs but I am quickly getting some. I have a shifting problem where I can shift through all gears without the engine running but as soon as I start the engine I can not select a gear. Yes, foot is on the brake and yes the pin is being pulled to go into reverse if I was to try going into reverse. The shift lever does not move. I adjusted the linkage to get more accurate shifting with the engine off so I know those are now correct. I opened the shift lever housing to inspect the teeth on the gear and found this picture below. Why is this oil so milky looking? I assume with oil like this I'll need to replace the wet clutch as well but am not positive. Does anyone have any input into how to flush this system and get things shifting correctly? Thanks in advance for all the help!
