When initially starting the ATV The left cylinder appears to fire as normal with burned exhaust gases. After about two minutes of operation the cylinder appears to stop firing as burned exhaust gases stop coming out of the pipe. At this point the engine will kill its self. What could be causing this problem? Thanks for any help given.

have you checked compression? check the compression. make sure your air filter is clean and youre jetted correctly. im guessing it might have something to do with your compression though.

check you coils wires too the black and orange ones they could be loose that will cause one cuyloinder to go out if one of them comes off

could it be caused by the reeds? I don't know if they'd couse those symptoms, but they will cause problems related to only one cylinder

does it blow any smoke... or is the cylinder completely d e a d!

flip reverse your spark plug wires and see if the problem jumps to the right cylinder. may tell you its an electrical problem
