I have a code 51!!!!! My wheeler is only running on one cylinder... I think a code 5 is a bas Injector... Has anyone else had a code 51??? or ever replaced an injector

 

wires might not making good contact on the injectors. i have only seen a few injectors go bad but they were running race fuel too

 

What bike is this on, and my 700 did this, and it was from water in the plug boot's, so first I would adjust the throttle cable to around an 1/8" slack, and then pull off the plug boots, and blow them out with compressed air, and also blow out, and wipe off the plug itself, and the inside of the boot, and then Lube them up VERY good with die electric grease, I did this for about the next 2 or 3 rides, and everything has been good for almost a year now
