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

Have a Coleman UTV 400 that cranks, runs, drives well until it gets warm and is put under load. Light throttle or full throttle it doesn't bog, but it will cut out mid throttle if you move the pedal quicker than it seems to like for example when you're getting ready to go up a hill, but if you immediately floor it, it will do just fine and not cut out. It's random if and when it's going to do it, but is consistent in that it happens only when hot/full operating temperature. I've replaced the injector twice, same with the spark plug and tried different heat ranges (NGK 7,8 and 8 iridium), replaced the fuel pump, adjusted the valves, checked air filter which is like new, changed the oil, replaced the fuel filter. No check engine light. I don't have a code reader for this. Initially I thought it might have a head or head gasket issue as when I got it, the oil was over full, very runny like water milky and it was smoking. I've changed the oil since then twice to clear and clean everything out, and it seems to be good. Coolant stays the same level and so does oil with no changes in consistency or need for adding more. Had I think 7-9 miles when I got it and now has about 77. What should I try or consider next?

As with any forum you join, there is a requirement for an obligatory introduction... and that seems fair. How else do you get that first post in there without jumping in with some stupid question right out of nowhere?
Hi. I'm Space Ghost. Well, not really, but that was my call sign on my last deployment before an IED made me non-deployable, and I an now retired/disabled, and living on my wonderful VA disability. I did almost 28 years in total between the Army, Army Reserve, and National Guard. 1 deployment with the Reserve (Desert Storm) and 3 with the Guard (1 pre, and 2 post 9/11)
Married (going on 30 years) one of each. (both out of the nest)
My vehicle is (at least not yet) not a UTV, however, it is an ATV, A 2001 Kawasaki Prairie 400.
BTW, That's Brandy, my former PTS/TBI service dog on the bike. RIP old girl. She's internet famous. Perhaps you've seen her before...
The reason I'm here is that Arthritis is starting to set into my wounds and my mobility is getting worse. I will be selling the quad bike soon, and going with a SXS, and have selected a Can Am model as the replacement, so I figured I had better get on board a forum somewhere. Just put in for my Guard retirement, and will be very soon looking to get into a Commander 6x6.
Wouldn't mind having the Limited with the Hvac system, but am really not sure it's worth the extra 10 grand or not. Plus it's 500 pounds heavier, and I prefer the doors off in nice weather. It's so much easier when working in the yard, and so much more fun when on the trail.
Anyway, I'm here now, so it will help me research more and make up my mind. Plus once I have it, I'll be able to share stories about it and of course, continue to learn more, as it will be my 1st sxs. Still have time before I get my retirement. Takes a good 90 days at least according to the guy I talked to... Typical government efficiency... lol.

Okay everyone, need some help here. I got my 2014 Bennche Bighorn 700 from my father inlaw. He has had it since new and as far as I know never had any problems with it until recently. It began with it being hard to start and having to give it some throttle for it to start up. Then it wouldn't stay running once it did start. If you go to start it, it will fire right off and only run for a split second and then die. If you give it some throttle it will start and stay running as long as your foot is on the pedal. While it's running its pretty rough and backfires. Here is a list of everything I've done so far. Initially I checked compression and it was low. I changed the cylinder, piston and rings. Took the head apart cleaned and laped the valves. Checked timing a few times. Adjusted the valves. New spark plug. Checked the air filter, it was fine. New battery. Changed the fuel pump because of a broken fitting. Changed the fuel filter, lines and fuel injector. Dumped the old fuel and put new in. Changed the air idle control, TPS, MAP sensor, Voltage Regulator, ECU and harness. I was getting codes 31, 107, 113 and 122 on the display. Once I changed the ECU no more codes have been displayed but still have the same issues. All fuses look good and as far as I can tell Grounds are good unless there are some I can't find. I'm at a loss here. Not really sure where to go. Compression was better after everything I did but I don't remember the numbers. I'll have to check it again if someone thinks that could be the issue. Any help would be greatly appreciated!
