Frustrated...

Hey guys,
I pulled out the spot where the spark plug supposedly is and all I found was a black stick going down into my engine. Sorry I don't have the correct terms to call them but I didn't find any spark plug connected to #3 in the illustration. Is this ok that I pulled this out and stuck it back in?

thats the right spot where the spark plug, is now put your spark plug wrench you got with your tool kit down in the hole

[Tuckin30's]

That looks like a 660?? If it is its going to be kinda deep down in that hole

Make sure there is no dirt or other crap around the plug befor you pull it dont need that stuff in engine.

be careful when putting plug back in make sure it starts easy, should be able to turn most of the way in by hand, then just a quarter to half turn with wrench.

X2 with what everyone has said!

The 660 plug is pretty deep in the head, can be more of a pain than other bikes to change.
When you put the spark plug wire and the long black thing on the end back in, make sure it pushes all the way on (should feel it click click click click as it slides onto the spark plug) Also make sure the black rubber seal on the end of the black plastic part sits properly back into the head so it keeps (or try to...) dirt out.

Remember the spark plug only requires 13 ftpounds of torque, you do not want to tighten it up very much at all.


Its a 18mm btw in case you dont have your Yamaha tool kit under the seat.

Some folks will put dielectric grease inside the sparkplug boot as well. Helps to seal out moisture.

[Grizzlyhunt]

Not sure if I have the tool kit but just incase I don't what size socket is it?

[Grizzlyhunt]

Thanks Rob I just saw your post on the socket size.

+ 10 on the dielectric grease!! Keeps u running when the water splashes up in the boot!!

[El Dee]

18mm if memory serves me correct and it could get real sketchy. I'll go to the shop in a bit and find out what size and get the new NGK # for you.

[Mad Mike]

maybe u should not be working on your griz. just say`n

[mudslinger828]

Make sure you put the plug boot on correctly. The boot has a v-shape to it , that goes to the bottom. If you don't put it on correctly you will have probs if you get in some deep water.
x2 on the dielectric grease.
