I have a 2021 Massimo MXU 1000. Last winter the front drive shaft sheared off inside the motor and it was cheaper to buy a new motor than to take it apart in order to remove the front drive shaft that was broken inside the case…
Now it is running rich, seems to maybe be geared too high, does not accelerate well once you hit about 28mph. I’ve replaced the O2 sensor. MAF is next (I accidentally ordered the wrong one, but when I removed the old one you can clearly smell fuel).
I’m not a motorhead but I can turn a wrench. Any ideas how to get this motor optimized? The motor has about 300 miles on it. I broke it in as recommended in the manual.

Hi everyone
Recently purchased a 2020 T-Boss 410 in what appears to be good condition
First time with this machine – I also have a diesel Kawasaki Mule which so far seems a better machine
It didn’t start and idle well particularly from cold when I got it and sudden take off ( now solved with new clutch parts ) was all or nothing !
I have replaced the idle valve, throttle position sensor, had the injector professionally checked ( ok) and also the pressure sensor this is a fuel injection engine, also plug and lead etc!
It still doesn’t run well and when starting I have to hold revs for a while as it wont idle but stall, thereafter its better and I have rebooted the ecu which has improved it
When I go to start it clicks as if there is a hydraulic lock and wont return after two or three attempts it then does turn over and start bit I need to give it a bit of throttle to start – is this normal ?
Is there adjustment for the air idle valve ?
The engine seems rough and with vibration compared to other engines I have been used to but some say this is normal?
I haven’t changed the Lambda sensor yet, anyone know how much difference this might make ( I have a new Bosch universal to fit )
Any advice very much appreciated, thanks

Anyone know anything about the Massimo Warrior 1000 MXD Crew UTV? I like the look but don't know anyone that owns one. All feedback is appreciated.

Recently, my unit Axis 500 (2020) will only go into reverse and neutral. I am not able to get high or low. The engine itself sounds fine and I do not have other issues on this unit. I change the engine oil but have not yet changed the gear oil.
Before this happened I occasionally encountered issue where going from reverse to high gear, it would grind some and i had to reposition to shift into high gear. I also for last couple weeks heard a squeaking sound. I couldn't tell what it was. Was looking for a grease point I missed.
The unit has around 70 hours and is kept in the garage.
Anyone else encounter this type of scenario? Any suggestions on troubleshooting would be appreciated. Thanks.
