Not enough info to even begin to tell you where to look.  What is the engine RPM when you're traveling 30 mph?  Is the engine running smoothly or acting like it's cutting out, missing or struggling?

I'm still guessing here.  Since the crankshaft position sensor didn't change anything, that could be the issue.  A bad sensor though would cause rough idle, slow engine resonse when you press on the accelerator, difficulty starting.    Engine starving from lack of fuel caused by a clogged fuel filter; low fuel pressure (should be about 50 psi) or bad throttle body.  A compression test might be of value.  Low compresson on all cylinders could indicate a jumped valve timing belt.  Not likely but it will eliminate one doubt.  3000 RPMs at 30 mph is normal; higher RPMs is not.

I'm leaning toward lack of fuel.  The engine is needing more fuel that what is being delivered.  Could be fuel pump, filter or the ECM isn't recognizing the demand for fuel from the throttle body.  Other than that, I'm sorry that my skill level is short of what I've suggested.  Good luck on fixing your machine.

I have a 2008 trooper t2 1100. I changed out the starter and now it will not do the 3 second warm up and start. Are their any shops in California that will still diagnose a Joyner Trooper, or does anybody know which signals can cause the warm up sequence to not go?

Donald 1968: Did you finally get your issue fixed on your trooper? If so what was the final fix?

California Nut Case: Did you ever find anyone to work on your Joyner, and if not what part of Cali are you in? I am a retired auto mechanic and live 30 minutes from Carson City Nv.  I bought my trooper because it is an automotive powertrain and I know I can fix it, modifying to use more common parts (ie Honda) when I need to. If you are fairly close I may be able to help.

      Joyner R2 2008 800cc ECM code reader Lite or OBD port install
      By staind
      Looking for information on installing a OBD port or a lite to read codes in ECM. 
      I can not find a OBD port or a lite to read codes on this R2 with 800cc. 
      I have code readers and adapters for most ATV's. From what I've found so far. They don't have a connection for to read codes. I may be wrong. That's why I'm asking. 
      This R2 has had new IAC, TPS, MAP, fuel pressure regulator and fuel pump replaced. This was done by neighbor to try to stop surging. It still surges on start up and then settles down. But once you hit the accelerator it revs up to 2000+ rpm and stays till you block off IAC port in throttle body with finger. Once you do that it once again settles down and idles perfectly.
      I want to know what the ECM is reading to help dio it.
      This joyner is the first one I've run across. Well second one in a week. (my neighbors 2 of them) The other was a trooper with the 1100cc chery motor that had been setting for years. After cleaning up the fuse box connections. It runs like a top. Had to replace all gages with aftermarket gages. Water, oil, gas, amp. Only problem one was the water temp using original sending unit. Had to install 150 ohm resistor on the input wire to get it to read correctly + - 5 degrees. Close enough. Gas sending unit was/is for a boat tank 6" tall. All SS so it should last forever. 
      thanks Dan D. aka staind

      Update of early Trooper Owners!!
      By rocmoc
      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.

      Joyner trooper Fuel injection
      By Nutcase
      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?
