This could be a few different things.

  1. First the stator contains a lighting coil and a sorce coil.(If just the sorce coil is bad you will get no spark but have lights) (if just the lighting coil is bad,you will get spark,but no lights)
  2. If the CDI is bad you can have lights with no spark as well.
  3. If the coil is bad,you can have lights without a spark.
  4. If the end of the spark plug wire is damaged,you can have light without a spark.
So,Go buy a spark plug tester and check to see if you have power at the spark plug cap while turning the motor over.
if not,start checking the items above.
If you do have power,replace the plug,The tool is 18mm and you can find it it under the seat in the air box area,inside the honda tool kit.

What size plug socket

Hi Johny, HD 6R12 spark plugs are gapped at 040" and take a 5/8 deep socket to R&R but there are/were some Screaming Eagle spark plugs that needed a 11/16 socket. Have nice day.

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.

Hey mate, i trying to change spark plugs and i am having problem removing it. Can you what is the easiest way of doing it.

No clearance??
Get a spark plug socket that has the hex shape on the outside of the top so you can put an open end wrench on the socket itself after you fit it onto the spark plug. There's no clearance for a ratchet, so try that.

What size spark plug socket do i need for my 1985 sp600 and where can i get it?

Hello, I don't know what size the socket you will need, but an easy way to find out is buy the spark plug(s) that is recommended for your bike, then go to an auto parts store with your plug, and find out what size socket you will need.

Engine is making a sucking sound

Sounds like when your bike backfired it blew the carb out of the intake boot. it is more common than you know on this model. just loosen the clamp and push it in untill it seats in the boot them tighten the clamp and go ahead and check the other clamps while you are at it. the spark plug socket is 18mm there should be one in your tool kit or you can buy one at most autoparts stores. Thanks

Changing Spark Plugs on 1999 Honda Shadow 750

Yes, it is an 18mm plug but you will need to use the Honda Plug Tool which is part of the stock tool kit just below the seat. Use that and you will get all of the plugs out very easily.
