Sounds to me like you may have an air leak. Inlet manifold & vacuum pipes are quite common. Hope this helps

Check the rectifier unit? Check how much power is being charged in to the battery it should be between 12/14 amps.

Hi do you mean the caliper fastening bolts, if so the 10 mm diamiter bolt torqe will be 24-26 ft pounds Or 33n meters

The timing is sett wrong,

All I can think of is poor quality capacitors maybe. There is no other reason that I can think of.

Friend, There could be two reasons for this. One. There is no current reaching the spark plug and thus there is no spark in the cylinder. Please remove the plug and connect again tot he HT wire. touch it to the body (metal portion) and turn the engine. If there is spark, it will show as blue flame between the points of the plug. Two. There is no gas reaching the cylinder. Ensure that it does reach there.

Reading this from manual,,Starter clutch inspection,,,remove the left engine cover and the idler gear.Try turning the starter clutch gear in both directions by hand.The gear should not turn at all to the left {counterclockwise}.It should turn freely and quietly to the right{clockwise}.If the gear fails to operate in that manner,the clutch is malfuncioning.This book covers alot of Kawasaki's from 73 to 1981 so I dont know if this will help.

More than likely the coil. Try the coil that feeds cylinders 1 and 4 wired in place of cylinder 2and 3 coil to prove it.

crank breathers usually located on top of engine block or ontop of the rocca cover

Could be a fuse or the ignition switch itself has shorted out. Check the fuses first.

check the ignition key switch is working , might have to dismantle it and make sure its making connections where it should !

Install new spark plugs and go easy on the throttle when starting. A power valve squirts extra gas every time the throttle is twisted. Twist too often when starting and the engine floods. Please rate my answer. Thanks!

hello Sir; maybe your crankcase bolt loose or crankcase gasket damage.

replace exhausts

Go to "Repair Manual".com and they have a very good service manual for the Mule. It's about 50 bucks but it's well worth the money. John

Hi and welcome to FixYa,

If all 4 have sparks and 1 cylinder is colder than the others, then it would be fuel starvation on that cylinder. Almost always, it would be a carb problem. The carbs would need to be pulled down, stripped & dis-assembled and all non-rubber parts soaked in carb cleaner. Particular attention/cleaning to the jets and all the small / pin holes. Note the number of turns on the air pilot screw. Ensure float works on all specially the one for the cylinder that is cold.

Good luck and thank you for asking FixYa.

you need to be more specific. More data.
