Spark plug

Look at the threads on all of the plugs you remove where they clean? Was the one that came out of that "HOLE" hard to get out? Did the store give you three of one plug and one of another??

Just some ideas.....



If all else fails you may have to use a thread restorer.....

are you sure you're threading the plug in straight? everything matching plug wise?

I've always called it a thread chaser. Probably find it at Checker Auto, Auto Zone, or such. It's like a tap from a tap and die that cleans out the spark plug thread in the head. I think for your Honda it should be 12mm, but bring a spark plug to be sure.

I was thinking that myself. its something that scares me about repairing threads while the head is still on the motor. metal shards in the cylinder=rebuild real fast.

I would do as said, and inspect the old plugs threads. But further, be sure to make sure you are screwing it in correctly. It might have to go in straight but it could also go in not straight.

threads in heads..

Apply some bearing grease to the thread chaser. Dont not run it all the way in. just go 1/2 to 3/4 turn then back out clean apply more grease and repeat.

The grease will catch the threads.

be careful not to run the thread chaser beyond the threads or you will have one hell of a time getting it out.

Unfortunately I just had to do this to the rear cylinder on my 2004 Yamaha Roadstar Warrior.

It works just be careful....

Plug size

Make sure that you get the right size/thread pitch. My Yamaha was a 12/1.25 I believe get the wrong pitch and you'll be right back where you started..

Yeah if you drop it in... you'll be pulling the head!
