I just bought a 2012 can am commander xt Rotax 1000 4x4 EFI. It has 456 Hours on it and 6543 miles on it. From what I have read that is not a hole lot. It will start Right up run for about 5 or 10 sec then starts to stubble and then stalls. And ever time I start it It runs fine for the first 5 or 10 sec.  I can Repeat the process for about 8 or 9 times and will will at least stay running. But it does not run fine until it is warmed up. Once it is up to operating temp it runs and drives fine. I have Replaced the fuel pump. Thinking that was the problem but no. I replace the map sensor It wouldn't even start with the new one in. So I put the old one back in and it started Right back up. I Think I had a bad map sensor. I will get a different one.  It Is definitely a fuel problem. I just don't know what kind of problem. Here Is my thinking on all the sensors. (Crank sensor) all that does is send a single to the coils. That don't care if the motor is cold or warm. (Map sensor) all that does is measure the temp of the air.(Fuel Injectors) If they were bad it would not start at all. If they were clogged. It would run like shit if it was cold or warm. (Temp sensor) This is the only sensor that tells the computer weather the engine is cold or warm. So what is the temp sensor is telling the computer that the engine is warm. When I first start it. the computer will think that the engine is at operating temp. So It leans out the fuel mixture.  So with a lean fuel mixture going into a cold engine. It Is going to stall.  I have no scan tool to hook up to the computer. So Please help. I am at my wits End trying to figure this thing out.

Let me start by saying, im not familiar with your specific model. However,  I have experienced the same symptoms that resulted from a bad TPS (throttle position sensor). 

Does your model have a tps and have you tested that component?

      I just purchased a 2023 Honda Pioneer a couple of weeks ago and had the hard roof and a front Honda Pioneer windshield installed at the shop before taking ownership. As things are drying up here in NC, the grass and dust are beginning to fly right through the back of the cab while driving. I was wondering if anyone has any good recommendations on rear windshields, dust panels, or mesh screens to help stop this?
      Thanks a lot!

      I have a 2011 or so Landmaster LM200.  I cannot get it to start.  I turn the key and nothing happens.  The brake switch seems to be working, the ignition switch works.  The Coil is new the Voltage Regulator is new and the starter relay is new.
       
      I can connect the terminals on the starter relay and it starts right up and runs fine.  I just can't get it to start by turning the key.
       
      I am having a bit of trouble bleeding the brakes, not much fluid comes out at the calipers when I am pumping the brakes, though that an air bubble near the brake switch might make it not sense that the brake pedal is depressed.
       
      I am at a loss, please help!

      Hope I posted this in the right place. Looking for the left side shaft carrier where the rear bearings go for an 1100cc sand viper, I understand an 800 cc carrier will also work. I need the old style two bearing with the spacer in the middle, the new style with just the one wide bearing wont work. If anybody has one I'll buy it right away. my email is [email protected]
