Spark plug wrench

[Anonymous]

Well, I need to go get a spark plug wrench. I tried a couple of sizes from my neighbor, (car ones) but none fit. What size should I get?


Reason I need it is that I finally got it all back together (sorta) and it won't fire up, so I was going to start with spark, move to fuel (having petcock problems after rebuild) and go from there.

most likely you'll need an 18 mm, if you cant find one for sparkplugs, take a regular 18mm deep well and stick a piece of fuel line in it to cushion the ceramic

If you are using standard NGK plugs, a standard 13/16" inch plug wrench shuld fit. That's about the same as a 20 or 21mm metric.

I found that i needed a thin wall socket also.

Mine is an 18mm for my NGK D8EA plugs on the GS1100E.

WHAT IS THE NUMBER OF YOUR SPARK PLUG AND DON'T YOU HAVE A REPAIR MANUAL?? MY 1100E HAS 18MM

As I recall he has a 16 valve GS750...that would require the same plugs as you and I, Scotty.

Why guess and check when you can very easily take the spark plug with you to a store? Unless you're ordering online...

Just a thought.

booboo, 'tis kinda hard to take it to the store when it's still attached to the bike, and the bike won't start, dontcha think?

I ended up with the 18mm and whatever the SAE is. My new plugs were one type, and the old were another...
