update to my problem. i found the fuse box. it was in battery compartment under driver seat, its got front and back waterproof covers, front one wasnt seated properly, full of mud and water. corosion starting. took it out blasted with hose, set out in sun all day to bake moisture out, then blasted it with WD. properly in stalled covers, smeared a little red rtv around the seems. hit the pin connectors with WD also. it didnt solve my problem, but im sure it prevented a near future problem. next im gonna  look were throttle cable ties in. stay tuned. TIC.

well i went through all the pin conecters at the intake/throttle body. everything looked ok. then made it to the ecu controller, pin conectors full of mud and water. 2pins on the ecu green corrotion at the base, bearly touched with tooth pick, they broke off. just ordered new one, from motorcycle doctor. i have to say after speaking to owner on  the phone , i dont feel like im alone in this anymore. really great guy. stay tuned.

ok 4th installment of the no go massimo. so it took so long, been working my tale off. then went to maine and ate 12 lobsters. the stuff craig sent me from motorcycle docter was most helpfull, gonna try to attach the service flash. well i got the ecu controller in couple days, that fixed that problem, but still wont start or idle unless you hold gas peddle , then it takes off, yes mine will start in any gear. well i had the intake tube off, were throtle cable attaches it has a cover, i removed to find linkage to the throttle position censor , there was a adjustment screw with a red cap over it, plus the houseing had a black rubber plug in it. my little voice told me to didtch the red cap over the screw head. when i put it back together. so now outta options, i pulled the black plug, stuck a straight slotted scewdriver in and turned clockwise, took almost a half turn, but problem solved. starts right up and idles perfectly. by the way the t.p.s is a cts brand, thats a high end american made company, all the high end guitar makers use them , tone and volume pots. craig told me that the engine came out of a yamaha grizzly.  but most important was my dipstick was marked wrong, not enough oil, clutch damage will happen. so i hopes this helps some other massimo owner. ps i just ordered a massimo mini bike

I have a 2018 Mossimo ALLI 700. Basically replaced everything. Worked directly with the great team at Motorcycle Doctor and SCAUTO. Replaced everything and for whatever reason the owner got into the UTV and drove it like he stole for 40 miles. Cannot stress enough if a buyer purchases a HISUN, BENNCHE or MOSSIMO off Walmart or Amazon they need strict break in instructions. 

Mossimo 700 would start with gas similar to a carburetor style setup. Please follow these steps if this is happening. 
1. Do a compression check...If you are under 100psi you have something blown or broke on the main head
2. We had 90 PSI so we started with the valves to see if they are staying open by adjusting them. They were in spec and timing was on mark
3. Head was removed to inspect valve springs. All were tight but one was loose. On the 700 the springs are single stage so it's tricky if you have an older one with dual stage springs because one can be snapped. 
4. In our case one of the single stage springs snapped and thank goodness nothing other than a broken spring created the lower compression. Spring replaced and valves readjusted running like a champ. You can feel a broken spring it will spin of feel loose versus all the good springs will be tight and not able to spin.

      My 800 sx with 75 hours is under warranty and began rough idle and unburned fuel coming out exhaust. I am located in eastern Arizona 5.5 hour drive from selling dealer (Bass Pro) in Mesa, Az. Called Tracker factory and they tell me there are dealers in Prescott and in Lake Havasu Az in far west Arizona. Tracker needs to find and appoint a dealer in Show Low Az if they want to compete with Polaris in the White Mountains. Show low is only 90 miles from me and I could live with that.

      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!

      New to the forum. New to UTVs. New to Electric motors.  I just got a 2021 Hisun Sector E to help with moving stuff on my  steep 5 acre wooded mountain patch. Plus I thought it would be fun on the gravel roads in the "neighborhood". Because we are remote and part time to the property, I didn't want the hassle of dumping out old gas or messing with oil and filters and all the usual maintenance of a ICE. But the biggest reason for me was the noise. I test drove the Axis utvs at Tractor Supply Co and they were LOUD. Seemed to ride rough too. If you want quiet, then electric is the way to go. But it does come with a high price tag. And all the electric models are still in their infancy. So its a bit of a gamble too. I bought the property for quiet. I wanted to keep it quiet.
      I liked that the Hisun had the dry cell batteries so there is no maintenance of checking and adding water. I'm a little worried about their lifespan especially after one person's poor utube review about them. But the dealer said the company took that to heart so hopefully changes were made for better batteries. There were no Lithium battery options available anywhere near me. Polaris is supposed to have one later this year. I liked that the Hisun came standard with roof, windshield, winch and trailer hitch. I have had the sector for only one day and worked it and road it good. So far I have a big smile on my face. I wish there was a category for this model on the forum here. Meanwhile, maybe folks will share their insights/ experiences on this thread. I'd like to learn as much about the sector e as I can. There isn't much info in the owners manual.

      I bought a used 2017 Warrior 800, with 92 hours on it. No problems with speed and power!!It's amazing! That being said my speedometer doesn't work. Everything else does tho.. Just the needle speedometer doesn't. Anyone have any ideals?I've checked fuses, was going to remove sensor but from the out side it looks ok. When driving  the gauge moves off the 0, but that's about it. Any help would be appreciated! thanks
