Hey Guys, I have been chasing a stalling condition for about two weeks now. The bike will crank up and idle fine, then after about 20 seconds it will fall on its face and stall. It happens at both idle and while running at various rpms. You can turn the key off, turn it back on and it will fire right back up without trouble. I have verified spark on both cylinders with a spark tester. I have also added an inline fuel filter, and pulled the injectors to verify proper pulse on each. Things I have replaced - (relearn procedure performed after each component replaced): spark plugs, ECU, relay/fuse box, fuel pump, & throttle position sensor - all with no improvement of the condition. The only warning light I get when the condition occurs is the oil lamp. The bike only has 14 miles. I am at a loss and appreciate any help and suggestions! Thanks

What do you mean by "relearn procedure"? ECU reset? How did you perform this?

Did this start with an outdoor temperature change? IE it ran fine when it was warmer out but now that it's cold it dies at idle.

If you give it a little gas does it stay running?

I'm wondering if the coolant temp sensor might be giving a false reading which would adjust the fuel map to where it won't idle

The ECU relearn procedure is done by holding the accelerator to WOT for 3-5 seconds and cutting the key off while @ WOT. I don't believe temperature is affecting it, I live in MS. The bike while die at any range in RPMS and giving it gas does not help keep it running. It just suddenly dies. No symptoms to lead me to believe it is a rich/lean condition or poor idle speed. Just shuts off but can turn the key off and back on and it fires right back up until it stalls again.

Check out the "Run Low on Oil" sender; make sure that it is plugged in and works.  Sounds to me that something like the oil sender has a timer and is causing your machine to shut down.

I guess I’m thinking along the same line as Motojoe. Does the oil light precede the shutdown, occur with shutdown or come on after the engine quits. In view of all the components you’ve replaced, I’d be looking hard at sensors. The more of these kind of problems I hear about, I think I’m going to invest in a code reader. Hope you saved all your old stuff for possible future use or sale.

Hey do me a favor and unplug both

your O2 sensors and let me know if it stops stalling

      2015 MSU-500 crank - no start
      By Prepper
      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.

      Can’t figure out what part I’m missing
      By Grant
      I recently bought an axis 500 and it’s missing a box or something the plug is L shaped I’ve looked through the wiring diagrams and still can’t figure it out. The plug is located right near the battery housing

      SXS No Crank at the Key and No Spark
      By Matthew Smith
      2013 Bennche Bighorn 700 EFI
       I just picked up this project that I was told would crank, but not start.  This is what I’ve figured out so far….
      I installed a new battery and get all dash lights, head lights, and brake lights on when turning the ignition on.  Fuel pump even turns on.  It does not crank with the key, but would when I jumped the starter solenoid, so I replaced it…..no change.
      Figured I’d check for spark and compression while I was dorking around.  Compression is 150 psi, but there is no spark.  Replaced the spark plug… no change.
      So, is my new starter solenoid bad?  Could it be the brake or gear position switches even though the brakes and neutral lights come on?  Not sure where to go from here.

      Bobcat 2200 dump bed relay pops fuse and stalls after warm
      By rdborra
      I had to remove the relay for the dump bed due to it popping the fuse for main key power. I have tried to find a short but nothing seems to out of normal. I also disconnected the dump motor and switch and still pops the fuse. Also, when the machine is warmed up i get about 5 to 10 of work out of before it stalls. Once I can get it to start again I have to use the choke to keep it running.

      No crank issue
      By Flanman55
      2007 Hisun HS700  will not crank.  Replace the ignition switch. Same thing.  Replaced solenoid by the battery same thing. Can jump it and it starts good across the solenoid posts. Ran a jumper wire from switch to solenoid. Nothing 
       
      can anyone suggest something else.
