You're going to need to helicoil it. If you can flip the engine upside down. If you can't do that, then apply grease to the drill bit, then the tap when you're cutting the threads. Go very slowly. Alternately snap-on and MAC tools make specially designed thread cutters that compress, go into the hole, then expand outwards to cut the threads. They have little cups to hold the shavings, but cost about $100 each.

Have a spark plug that blew out on a honda jazz


If you are lucky, the spark plug was not tightened correctly and worked loose. In this case, you may be able to chase the threads and it will go back in and stay. Make sure the plug is installed correctly this time.

If you are unlucky, the threads will be stripped. In this case, you have 2 choices: thread repair or larger spark plug. Either way, you have to drill and tap the spark plug hole without getting any metal shavings in the cylinder. The main difference is that if you use a thread repair insert, the original spark plug size will fit in your engine; if you tap out the holewithout using an insert you will have to get a different spark plug for the cylinder that was repaired.

How to change spark plugs



REMOVAL PROCEDURE
  1. Remove the ignition control modules.
  2. Clean the spark plug recess area with low pressure air.
CAUTION: Wear safety glasses when using compressed air, as flying dirt particles may cause eye injury.

NOTE: Clean the spark plug recess area before removing the spark plug. Failure to do so could result in engine damage because of dirt or foreign material entering the cylinder head, or by the contamination of the cylinder head threads. The contaminated threads may prevent the proper seating of the new plug. Use a thread chaser to clean the threads of any contamination.

  1. Remove the spark plugs from the cylinder heads.
NOTE: Allow the engine to cool before removing the spark plugs. Attempting to remove the spark plugs from a hot engine may cause the plug threads to seize, causing damage to cylinder head threads.
  1. Inspect the spark plugs. Refer to Spark Plug Inspection.
INSTALLATION PROCEDURE
  1. Measure the spark plug gap on the spark plugs to be installed. Compare the measurement to the gap specifications.
NOTE:
  • Use only the spark plugs specified for use in the vehicle. Do not install spark plugs that are either hotter or colder than those specified for the vehicle. Installing spark plugs of another type can severely damage the engine.
  • Check the gap of all new and reconditioned spark plugs before installation. The pre-set gaps may have changed during handling. Use a round feeler gage to ensure an accurate check. Installing the spark plugs with the wrong gap can cause poor engine performance and may even damage the engine.
117381099
  1. Install the spark plugs to the cylinder heads.
NOTE:
  • Be sure that the spark plug threads smoothly into the cylinder head and the spark plug is fully seated. Use a thread chaser, if necessary, to clean threads in the cylinder head. Cross-threading or failing to fully seat the spark plug can cause overheating of the plug, exhaust blow-by, or thread damage.
  • Refer to Component Fastener Tightening Notice in Service Precautions.
Tighten the spark plugs to 20 N.m (15 lb ft) .
  1. Install the ignition control modules.

Not starting


Look under the gas tank near the top of engine - find a large black wire (about size of a pencil in thickness) it will end at the top of your spark plug, 1 on each side of the engine on my 650, first remove rubber boot, second apply plug socket (should be one in your tool kit) if not buy one to fit. A spark plug socket has rubber inside it prevents damage to the plug, remove spark plug, remember righty tighty and lefty loosey, check the gap set on the plugs, just ask the guy at the store to check it when you buy them, you will learn how to do it if you just watch, insert new plug using your fingers only, dont force it! you want to start the threads correctly and not cross thread the spark plugs, you should be able to get several turns by hand/fingers alone - tighten - but dont over tighten the spark plug, it not good. Then pop the boot back on the new plug and repeat on the other side of the bike. NOTE: I have to remove the aluminum insulator on top of the new spark plugs to put the spark plug boots back on, its threaded also so lefty loosey etc, you may need to also. Charge the battery while you are doing this and have some starting fluid/ether nearby. if the bike is cranking but wont fire you have other issues.

What is the correct torque for spark plug installation?


Plug torque is not critical. Best way to tighten them is to run them in finger tight to make sure the they are not cross threaded, then tighten enough that you feel the gasket crush. (plug bottomed and just a bit more).
It is essential that you use anti-seize compound on the threads. That will prevent the plugs from seizing into the heads and snapping or tearing the threads out when removing the next time.

Multiple cylinder misfire


Carefully inspect the threads it sounds as if you have a crossthreaded hole that isn't allowing the plug to full seat. You'll need to get the proper size threading die and very carefully recut the threads. Best done in a shop as if anything falls into the cylinder your looking at very expensive repairs. It happens quite frequently with aluminium blocks and needs to be fixed as a spark plug popping out lets hot fuel dump into the engine compartment. Here is a description of such a tool at toolmonger.

It can happen to the best of us: one moment of inattention results in a cross-threaded spark plug hole. You can either install a helicoil and hope for the best, or send it out to have the whole shebang re-tapped. Now you have another option. The Back-Tap can fix that cross-threaded hole from the inside — without pulling the head.
The Back-Tap is a tap with expandable threads and a mandrel to catch errant metal shards. Apply a dab of grease to the mandrel, then place the device in the hole past the damaged threads. As you back it out, the cutters expand out to engage the undamaged threads, then gently reshape the damaged ones. The greased mandrel keeps metal filings from ending up in the cylinder.
The result: a task that could potentially take days and cost hundreds of dollars is done in minutes for less than a hundred bucks.
MAC offers a three-piece kit that includes a 10mm, 12mm, and 14mm Back-Tap for $90. You can buy Individual taps from various sources for about $50 each.

you can put a little bit of oil on the treads to get it started. Do not cross tread it because it will strip the hole out and you will have to replace everything.
