There can be a misfire too from the cylinders.
An engine that
hesitates, stumbles or misfires when accelerating or when
it is under load is an engine that is either sucking too much air, not
getting enough fuel or misfiring. If the Check Engine Light comes on,
you may find any of the following codes:
• P0171, P0174 Lean
fuel condition codes
• P0120 to P0124 Throttle position sensor codes
•
P0222 to P0229 Throttle position sensor codes
• P0400 to P0409 EGR
related codes
If there are no misfire codes, a common cause of
acceleration stumble is a bad throttle position sensor (TPS). The TPS
tells the computer how far the throttle is open. The computer uses this
information to determine how much fuel is needed to maintain the correct
air/fuel mixture and when extra fuel is needed if the throttle suddenly
opens wide.
Another common cause is dirty fuel injectors. If
varnish deposits have built up in the tips of the injectors, they won’t
spray as much fuel as they normally do, or will “dribble” fuel instead
of spraying a fine mist. This creates a lean fuel mixture and
conditions that are ripe for stumble and hesitation (also misfire). Look
at short term fuel trim (STFT) and long term fuel trim (LTFT) with your
scantool.
If the numbers are high, it tells you the engine is running lean and
the injectors need cleaning. Treat mild cases with a high quality
fuel-injector cleaner additive. Severe cases require professional
cleaning equipment.
Also if this sensors apply to your
vehicle, camshaft sensor or
crankshaft sensor if sensors bad you don't get any spark.
Good
luck and rate this solution,
please.

check cable, spark plug, spark plug cap for good resistance levels. then check the coil. easy fix.

Code 0 (no flashes) - The system is functioning normally
Code 1 (one flash) - Electronic control unit
Code 2 (two flashes) - Shift Switch or it's circuit
Code 3 (three flashes) - Angle sensor or it's circuit
Code 4 (four flashes) - Gear position switch or it's circuit
Code 5 (five flashes) - ECU motor circuit (defective ECU)
Code 6 (six flashes) - ECU failsafe relay circuit (defective ECU)
Code 7 (seven flashes) - ECU voltage converter circuit (defective ECU)
Code 8 (eight flashes) - Angle sensor, control motor, ECU or circuit
Code 9 (nine flashes) - Angle sensor, it's circuit or ECU
Code 10 (ten flashes) - Pulse generator or it's circuit
Code 11 (eleven flashes) - Speed Sensor , it's circuit or ECU
Code 12 (twelve flashes) - Gear position switch, it's circuit or ECU
I hope this helps you out.
Where can I find the exact timing sequence for a
every four wheeler I've ever worked on has the ignition timing fixed and controlled by the CDI. Mechanical timing usually invovles lining up the T on the flywheel with a mark on the cam shaft. you'll need a service manual for more specifics.

My first check would be the condition of the chain and sprockets. Check to make sure all of the teeth are still ok and if the tension of the chain is correct and that it is well lubed.If the noise is more pronounced from the rear and chain and sprockets are ok, it could be the differential that has either failed bearings or damaged gears.
Dropped small screwdriver down sparkplug
your going to need a magnet on a flexible shaft and lots and lots of patience , get a chair you will need it. Only one other thing I can say is if that doesnt work., the cylinder head needs to come off.
My 2000 honda rancher has recently started to die
that is just a hand primer for when you run out of fuel. you may need to change the fuel filter. and clean out the fuel chamber and veins in the carb. if filter is old 2 years then it should be changed.

Suspect rings or blown head gasket. Do a compression test. Look at the oil. Milky? Look at the water. Oily?

Hi Shawn, Check the ignition timing and inlet manifold gaskets and all vacuum hose connections. If all is okay carry out a compression test, looking specifically for burned valves, but timing would seem to be the likely problem. Regards John
