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

Does Anyone by chance have a owners manual and a shop manual for a 2007 800cc trooper. I just bought one and need to figure out where and how to engage and disengage the 4 wheel drive. Is it electronic or is there a hidden lever. PLEASE HELP

This is rocmoc/Michael one of the first on this forum when the Joyner was one of the most active topics. First an update of others. The earlier members will also remember Lenny and Jeff. With myself we organized the first Jamborees in 2009-2012. Sadly if you have not heard we lost both Lenny and Jeff in 2018. A great loss to the community. Myself: Still around but rolled over to Jeep and Arctic Cat Wildcat. The Wildcat design still remains me of my old 2008 Trooper. Doing well as the Last Man Standing but cleaning out the garage. Found some New and used Trooper parts I will list in the parts section. Wanted to give you all a chance before I list on Ebay. As many of you knew Lenny listed a lot of stuff on Ebay. Will I partnered a lot of the stuff with him and I still have stuff. Take care and I will check in for message should you want to ride. Still make it to Utah every other year and am still in Southern AZ.

I have a Joyner Trooper 1100 4 place that has been sitting for a number of years. I have everything taken care of but i can't get the fuel through the injectors. Fuel pump puts full pressure on them but they don't turn on or spray fuel. Any ideas?

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!
