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

I have an Axis 500 4x4 UTV that I was given. It looks like an almost new machine with 39 hrs on it however it was apparently under water from the hurricane . I have no spark at the plug. I have replaced the plug, the plug wire, & the stator so far. Can anyone advise me of what i need to check and or replace to get this thing running? Any advise would be greatly appreciated.
Thank You,
D Maynard

I'm working with a 2015 MSU-500. Basic symptoms are it cranks well, but will not fire. It has spark, and it has fuel spraying out of the injector (and spraying starting fluid into the throttle body and plug hole makes no difference). It has compression. I bought it not running, and no other information was available. It has 775 miles on it and 127 hours. It looks to be in very good shape. Previous owner replaced fuel pump, ECU, coil, plug, and the fuse/relay box that mounts on the firewall, then gave up.
My questions relate to cam/valve timing, considering the symptoms and diagnostics so far. My thinking was the woodruff key sheared off and the crank spun, making it out of time. My question is, by the pictures attached does anyone have an opinion as to the cam/valve timing being correct? In the crankshaft picture you can see a timing mark visible. In the camshaft picture I have arrows directed towards what I think are timing marks (which appear to be exactly 180 degrees from one another). However, the long arrow in what appears to be bolt configuration in line with the piston/rod line. Here is a puzzling note... in the position you see in the pictures... I have valve lash on both the intake and exhaust. I think it's at TDC, given the visible crank timing mark and valve lash on both valves.
Any thoughts ? Does this appear to be in proper valve time ? Have I missed anything simple ? Thanks in advance for your input.

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.
